from Wikipedia

In Hindu philosophy, turiya (Sanskrit: तुरीय, meaning "the fourth"), also referred to as chaturiya or chaturtha, is the true self (atman) beyond the three common states of consciousness (waking, dreaming, and dreamless deep sleep). It is postulated in several Upanishads and explicated in Gaudapada's Mandukya Karika.

Upanishads

[edit]

Turiya as 'the fourth' is referred to in a number of principal Upanishads.[1] One of the earliest mentions of the phrase turiya, "fourth", is in verse 5.14.3 of the Brihadaranyaka Upanishad, referring to a 'fourth foot' of the Gayatri Mantra, the first, second and third foot being the 24 syllables of this mantra:

Then there is that fourth (turiya) vivid foot of the Gayatri, which is none other than the sun blazing beyond the sky. The term turiya means the same thing as 'fourth'(caturtha). 'Vivid foot' for the sunblazes beyond the entire expanse of the sky. A man who knows this foot of the Gayatri in this way will likewise blaze with splendour and fame.[2][note 1]

According to Raju, chapter 8.7 through 8.12 of the Chandogya Upanishad, though not mentioning turiya, 'anticipate' the Mandukya Upanishad and it's treatment of turiya.[note 2] These verses of the Chandogya Upanishad set out a dialogue between Indra and Virocana, in search of atman, the immortal perceiver, and Prajapati, their teacher. After rejecting the physical body, the dream self, and the dreamless sleep (in which there is no perception of "I am") as atman, Prajapati declares in verse 12 to Indra that the mortal body is the abode of the "immortal and non-bodily self", which is the perceiver, the one who perceives due to the faculties of the senses.[3]

The phrase "turiya" also appears in Maitri Upanishad in sections 6.19 (in the context of yoga) and 7.11:

Now, it has elsewhere been said: 'Verily, when a knower has restrained his mind from the external, and the breathing spirit (prāṇa) has put to rest objects of sense, there-upon let him continue void of conceptions. Since the living individual (jīva) who is named "breathing spirit" has arisen here from what is not breathing spirit, therefore, verily, let the breathing spirit restrain his breathing spirit in what is called the fourth condition (tiwya)' For thus has it been said:-

That which is non-thought, [yet] which stands in the midst of thought,
The unthinkable, supreme mystery! —
Thereon let one concentrate his thought

And the subtle body (linga), too, without support.

— Maitri Upanishad, Section 6.19[4]

7.11: He who sees with the eye, and he who moves in dreams,

He who is deep asleep, and he who is beyond the deep sleeper —
These are a person's four distinct conditions.

Of these the fourth (turya) is greater [than the rest].

— Maitri Upanishad, Section 7.11[5]

Verse 7 of the Mandukya Upanishad refers to "the fourth" (caturtha),[6] or "the fourth quarter",[7] the first, second and third quarter being situated in the waking, dreaming and dreamless state:

They consider the fourth quarter as perceiving neither what is inside nor what is outside, nor even both together; not as a mass of perception, neither as perceiving nor as not perceiving; as unseen; as beyond the reach of ordinary transaction; as ungraspable; as without distinguishing marks; as unthinkable; as indescribable; as one whose essence is the perception of itself alone; as the cessation of the visible world; as tranquil; as auspicious; as without a second. That is the self (atman), and is that which should be perceived.[7]

Michael Comans disagrees with Nakamura's suggestion that "the concept of the fourth realm (caturtha) was perhaps influenced by the Sunyata of Mahayana Buddhism",[8][note 3] stating that "[T]here can be no suggestion that the teaching about the underlying Self as contained in the Mandukya contains shows any trace of Buddhist thought, as this teaching can be traced to the pre-Buddhist Brhadaranyaka Upanishad."[8]

According to Ellen Goldberg, this fourth quarter describes a state of meditation; the insight during meditation of Turiya is known as amātra, the 'immeasurable' or 'measureless' in the Mandukya Upanishad, being synonymous with samādhi in Yoga terminology.[9]

AUM and four states of consciousness

[edit]

In the Mandukya Upanishad, AUM symbolizes the four states of conciousness. The three parts in A-U-M corresponds to waking, dreaming, and sleep states.[10] The fourth state, (turīya avasthā), corresponds to silence, just as the other three correspond to AUM. It is the substratum of the other three states. It is, states Nakamura, atyanta-shunyata (absolute emptiness).[11] According to Sharma, Turiya is "the common ground of all these states. It manifests itself in these three states and yet in its own nature it transcends them all".[10]

Advaita Vedanta

[edit]

Gaudapada

[edit]

Gaudapada, an early guru in Advaita Vedanta, was the author or compiler[12][note 4] of the Māṇḍukya Kārikā, a commentary on the Māṇḍukya Upanishad, also known as the Gauḍapāda Kārikā and as the Āgama Śāstra. Gaudapada was influenced by Buddhism,[13] though he was a Vedantin and not a Buddhist.[13] In the Māṇḍukya Kārikā, Gaudapada deals with perception, idealism, causality, truth, and reality.[11] In his commentary on verse 7 of the Mandukya Upanishad, Gaudapada explains Turiya, the fourth state of consciousness, as the ultimate reality that transcends the waking, dreaming, and the deep sleep states. According to Gaudapada, Turiya is beyond cause and effect and is the pure, self-luminous consciousness in which all dualistic distinctions between subject and object cease to exist. The phenomenal world is an appearance produced by maya (illusion), while Turiya is the non-dual reality.[14] For Gaudapada, turiya is the "true 'state' of experience," in which the infinite (ananta) and non-different (advaita/abheda) are apprehended.[15]

Isaeva notes that the Mandukya Upanishad asserts that "the world of individual souls and external objects is just a projection of one indivisible consciousness (citta)," which is "identical with the eternal and immutable atman of the Upanisads [..] in contrast to momentary vijnana taught by the Buddhist schools."[16][note 5]

Adi Shankara

[edit]

Adi Shankara described, on the basis of the ideas propounded in the Mandukya Upanishad, the three states of consciousness, namely waking (jågrata), dreaming (svapna), and deep sleep (susupti):[web 1][web 2]

  • The first state is that of waking consciousness, in which we are aware of our daily world. "It is described as outward-knowing (bahish-prajnya), gross (sthula) and universal (vaishvanara)".[web 2] This is the gross body.
  • The second state is that of the dreaming mind. "It is described as inward-knowing (antah-prajnya), subtle (pravivikta), and burning (taijasa)".[web 2] This is the subtle body.
  • The third state is the state of deep sleep. In this state, the underlying ground of consciousness is undistracted. "[T]he Lord of all (sarv’-eshvara), the knower of all (sarva-jnya), the inner controller (antar-yami), the source of all (yonih sarvasya), the origin and dissolution of created things (prabhav-apyayau hi bhutanam)".[web 2] This is the causal body.

Turiya is liberation, the autonomous realization of the non-causal Brahman beyond and underlying these three states.[17][18][19][20][21]

Kashmir Shaivism

[edit]

Kashmir Shaivism holds the state called turya – the fourth state. It is neither wakefulness, dreaming, nor deep sleep. In reality, it exists in the junction between any of these three states, i.e. between waking and dreaming, between dreaming and deep sleep, and between deep sleep and waking.[citation needed] In Kashmir Shaivism there exists a fifth state of consciousness called Turiyatita - the state beyond Turiya. Turiyatita, also called the void or shunya is the state where one attains liberation otherwise known as jivanmukti or moksha.[citation needed]

Based on the Tantraloka an extended model of seven consecutive stages of turiya is presented by Swami Lakshman Joo.[citation needed] These stages are called:

  1. Nijānanda
  2. Nirānanda
  3. Parānanda
  4. Brahmānanda
  5. Mahānanda
  6. Chidānanda
  7. Jagadānanda

While turiya stages 1 - 6 are attributed to the "internal subjective samādhi" (nimīlanā samādhi), once samādhi becomes permanently established in the seventh turiya stage it is described to span not only the internal subjective world anymore but beyond that also the whole external objective world (unimīlanā samādhi).

Turiya, also known as the fourth state of consciousness, is a central concept in , particularly within the tradition, where it represents the transcendent, non-dual reality of pure awareness that underlies and surpasses the three ordinary states of waking (jagrat), dreaming (svapna), and (sushupti). As described in the , Turiya is neither inwardly nor outwardly cognitive, ungraspable, without distinctive marks, and characterized by the cessation of all development, embodying the essence of the Self as one with , the ultimate reality. In the Mandukya Upanishad, the syllable Om (AUM) symbolizes the four states: the sound A corresponds to waking, U to dreaming, M to deep sleep, and the silence following it to Turiya, illustrating how this fourth state integrates and transcends the others as the substratum of all experience. Shankara's commentary on the text emphasizes Turiya as the true nature of the Atman, free from duality, where all distinctions dissolve into blissful unity, attainable through self-inquiry and meditation. This state is not a mere alteration of consciousness but the eternal, unchanging witness to the flux of the other three, often realized in practices like Samadhi. Turiya holds profound significance in Vedantic metaphysics as the realization of non-duality (Advaita), where the individual self merges with the universal , ending the cycle of ignorance and suffering (samsara). Gaudapada's Karika, a key gloss on the Upanishad, further elucidates Turiya as beyond causation and , reinforcing its role as the ground of being from which the apparent arises like a dream. In contemporary contexts, Turiya-inspired meditative techniques, such as , have been studied for their potential to foster this state, linking it to reduced stress and enhanced through .

Etymology and Core Concept

Linguistic Origins

The term Turīya derives from the ordinal form turīya, rooted in catúr (four), denoting "the fourth" and thereby distinguishing it from the three common states of jāgrat (waking), svapna (dreaming), and suṣupti (). This emphasizes its position as a transcendent category beyond the triad of experiential states. Although instances of turīya appear in earlier Vedic literature, such as the Rig Veda, often in numerical or instrumental senses (e.g., related to quarters or sounds), its first explicit philosophical usage as the fourth state of occurs in the Māṇḍūkya Upaniṣad, dated to around the 1st century CE in the post-Vedic period, though scholars debate the exact timing with estimates ranging from the 1st century BCE to the 2nd century CE. This marks a pivotal terminological evolution from general ordinal usage to a specialized metaphysical concept. Transliteration variations include "" (short i) and "Turīya" (with macron on ī in IAST), reflecting scholarly conventions in rendering . In English translations, it is typically rendered as "the fourth state" or "pure consciousness," capturing its abstract essence without implying a temporal sequence. The term has also influenced expressions like caturtha (another form for "fourth") across broader Indic languages, such as and , where similar ordinal derivations appear in philosophical discourses.

Definition in Consciousness States

In , particularly within the framework of , consciousness is understood to manifest in three primary empirical states, with a fourth transcendent state known as Turiya. The waking state, termed jāgrat or viśva, involves external awareness through the senses, where the individual perceives gross objects in the physical world, engaging in subject-object duality. The dreaming state, svapna or taijasa, shifts to internal imagery, where the mind constructs subtle objects from impressions, still maintaining a sense of duality but without direct sensory input from the external environment. Finally, the deep sleep state, suṣupti or prājña, represents undifferentiated rest, characterized by the absence of mental activity and objects, yet containing latent bliss and serving as the seed for the other states, though veiled by . Turiya, the fourth state, transcends these three empirical modes as a non-dual, self-luminous awareness that exists beyond subject-object duality, often identified with the of or Ātman. It is eternal and unchanging, serving as the silent witness to all states of without being affected by them, and is the source of supreme bliss (). Unlike the transient nature of waking, , and , Turiya is partless, omniscient, and free from birth or decay, representing pure that underlies and pervades all experience. Symbolically, Turiya is represented in the through the syllable AUM, where the sounds "A," "U," and "M" correspond to the waking, dreaming, and states, respectively, while Turiya is indicated by the following their utterance, signifying its transcendence beyond all phenomenal manifestation. This quaternary structure underscores Turiya's role as the unifying essence, where the three lower states dissolve into its non-dual reality upon realization.

Scriptural Foundations

Mandukya Upanishad

The , the shortest among the principal with just 12 verses, is appended to the Atharva Veda and centers solely on the sacred syllable as a symbol of ultimate reality, elucidating the four states of consciousness through which the (Atman) is realized as . Composed circa the 1st millennium BCE, it provides a concise framework for understanding the progression from empirical awareness to transcendent unity, without narrative dialogues typical of other . The Upanishad opens with verses 1–3, defining the three common states of consciousness. Verse 1 identifies Om as encompassing all that is past, present, future, and beyond, equating it with Brahman and the Self divided into four quarters. Verse 2 introduces these quarters: the waking state (Vaiśvānara or Viśva), the dream state (Taijasa), the deep sleep state (Prājña), and the fourth (Turīya). Verse 3 details Vaiśvānara as the waking state, where consciousness turns outward to perceive gross external objects through seven limbs (head, eyes, etc.) and nineteen mouths (senses and faculties), enjoying material experiences. Verses 4–6 describe the dream and deep sleep states. Verse 4 portrays Taijasa as the dream state, with consciousness turned inward to subtle objects created from impressions, sharing the same seven limbs and nineteen mouths as the waking state. Verse 5 depicts Prājña in deep sleep as a unified mass of consciousness, free from desires, dreams, and duality, characterized by bliss and serving as the source from which waking and dream arise. Verse 6 affirms Prājña as the lord of all, the inner controller, and the origin of phenomena, yet distinct from Turīya, which transcends empirical grasp. Verse 7 defines Turīya as the fourth state, not conscious of internal or external objects, beyond the triad of experiencer, experienced, and experience; it is pure consciousness (caitanya), non-dual, auspicious, and ineffable, witnessing all states without attributes. Verses 8–12 link these states to Om's phonetic components, prescribing meditation for realization. Verse 8 states that Om, the whole, corresponds to the Self's quarters, with its letters (A, U, M) representing the first three states and the succeeding silence Turīya. Verse 9 associates A (the first sound, from the throat) with Vaiśvānara, promising fulfillment of desires and worldly success for its meditator. Verse 10 ties U (the second, prolonged sound) to Taijasa, fostering knowledge, equality among seekers, and spiritual merit. Verse 11 connects M (the third, buzzing sound) to Prājña, where all dissolves, granting insight into Om's essence and absorption into the Self. Verse 12 culminates with the soundless resonance after Om as Turīya, partless and auspicious, leading the wise to non-dual realization where the seen merges into the seer.

References in Other Upanishads

In the , the concept of Turiya finds an early allusion through the description of the as the subtle witness transcending phenomenal states. Verse 6.8.7 declares, "That which is the subtlest of all is the of all this. It is the Truth. It is the . That thou art, O Śvetaketu," portraying the ātman as an unchanging essence beyond names, forms, and dualities, serving as the underlying reality that witnesses waking and other conditions without being affected by them. The elaborates on a similar transcendent in its discussion of states, particularly in section 4.3. Verses 21–30 depict the in as luminous with pure (prajñāna), where it does not perceive objects yet remains the source of : "When there, the self does not see; for although seeing then, it does not see... It is because of the light of that pure intelligence that the self becomes the light in the state of dreamless sleep." This portrayal of an undifferentiated, self-luminous beyond sensory engagement prefigures Turiya as the foundational integrating all states. The Taittiriya Upanishad presents the layers of the self (kośas) in a progressive model that implies Turiya through the culmination of sheaths. It outlines five enclosures—annamaya (food), prāṇamaya (vital energy), manomaya (mind), vijñānamaya (intellect), and anandamaya (bliss)—with the anandamaya kośa as the innermost layer of subtle joy, beyond which lies the infinite Brahman: "Different from this bliss sheath is the person consisting of bliss" (2.8.1), suggesting Turiya as the pure, non-enclosed ātman that envelops and transcends these veils. Explicit reference to the "caturtha" (fourth) state appears in the Maitri Upanishad, particularly in the context of meditative realization. Verses 6.18–19 describe the yogic ascent through breath control and inner focus, leading to the fourth state: "The fourth is the state of the all-knowing, the supreme Lord, who is the witness of all, beyond the three states, without qualities." This positions Turiya as the meditative pinnacle where the practitioner merges into non-dual . The notion of Turiya evolves across the from implicit hints in earlier texts like the Chandogya and Brihadaranyaka, which emphasize the ātman's witnessing role beyond transient states, to more explicit formulations in later ones such as the Maitri, integrating it fully into the of the singular, eternal as the ground of all existence. This progression reflects a deepening synthesis of models with the broader ātman-Brahman identity.

Advaita Vedanta Interpretations

Gaudapada's Contributions

Gaudapada, a philosopher active in the 7th to 8th century CE, played a pivotal role in the development of Advaita Vedanta through his authorship of the Mandukya Karika, also referred to as the Agama Shastra. This text comprises 215 verses organized into four chapters and serves as a metrical commentary on the Mandukya Upanishad, expanding its brief exposition on the states of consciousness. As the paramaguru (preceptor's preceptor) of Adi Shankara, Gaudapada's work laid the groundwork for non-dualistic interpretations of Turiya, emphasizing its status as the ultimate, unchanging reality beyond empirical experience. The structure of the Mandukya Karika systematically builds toward a non-dual understanding of Turiya. The first chapter, Agama Prakarana (29 verses), directly interprets the Upanishad's analysis of the three states—waking (jagrat), dreaming (svapna), and deep sleep (sushupti)—while introducing Turiya as the fourth, attributeless consciousness that transcends and unifies them, described as "free from all verbal designations and devoid of phenomenal attributes." The second chapter, Vaitathya Prakarana (38 verses), argues for the illusory nature of the perceived world by likening it to a dream, where apparent multiplicity arises without true origination. The third chapter, Advaita Prakarana (48 verses), and the fourth, Alatasanti Prakarana (100 verses), advance the doctrine of ajativada (non-origination), asserting that nothing ever truly comes into being, as all phenomena are mere appearances without substantial reality. Central to Gaudapada's contributions is the conception of Turiya as the only existent reality, with the three states functioning as illusory projections (vivarta) upon this non-dual substratum, akin to how a is misperceived as a snake in dim light. This vivarta theory underscores that the world of duality is not a real transformation but a (adhyasa) on the (atman), which is identical with . Through such analogies and logical analysis, establishes Turiya not merely as a meditative state but as the eternal, birthless essence free from causation and change. Although firmly rooted in Vedantic tradition, Gaudapada's exposition of Turiya exhibits notable parallels with , particularly the concept of shunyata () in its denial of inherent existence in phenomena, as seen in the Karika's emphasis on non-origination and the illusoriness of samsara. These influences, drawn from and Yogacara schools, enrich the non-dual framework without compromising its Upanishadic foundation, positioning the Mandukya Karika as a bridge between Indian philosophical currents.

Adi Shankara's Elaborations

, in his eighth-century commentary known as the Māṇḍūkya Kārikā Bhāṣya, elaborates on Turiya as the non-dual reality that transcends and encompasses the three states of consciousness—waking, dreaming, and —identifying it unequivocally as , which is identical to the individual Atman. He describes Turiya as eternal, unchanging, birthless, and self-luminous, serving as the sole substratum upon which the illusory manifold of the universe is superimposed, much like a mistaken for a snake. This affirmation aligns with Vedic orthodoxy, where Turiya represents the ultimate truth free from all duality and attributes, rendering the apparent world as mere illusion (māyā). While commenting on Gaudapada's foundational kārikās, Shankara critiques interpretations that draw excessive parallels to Buddhist philosophies, such as the Vijñānavāda school's notion of momentary consciousness or the idea of voidness (), insisting that Advaita's non-dual Atman is self-evident and distinct from such transient or nihilistic views. He emphasizes vivartavāda, the doctrine of apparent transformation, over (non-origination), explaining that the arises as an illusory projection of through (avidyā), without any real modification of the underlying . In this framework, Turiya functions as the unchanging substratum beneath avidyā, unaffected by the superimpositions of duality that create the experiences of the three states. Shankara integrates Turiya into the broader Upanishadic tradition by linking it to the Chāndogya Upaniṣad's mahāvākya "Tat Tvam Asi" ("That thou art"), which reveals the essential identity between the individual self and , thereby facilitating the realization of Turiya as the non-dual essence shared across scriptures. On the practical front, he outlines jñāna yoga as the means to attain this realization, involving śravaṇa (scriptural study), manana (logical reflection to dispel doubts), and nididhyāsana (profound meditation) on symbols like Aum, which guide the seeker to negate superimpositions and directly cognize Turiya through disciplined inquiry and renunciation.

Perspectives in Other Traditions

Kashmir Shaivism

, a non-dualistic Tantric tradition flourishing between the 9th and 11th centuries CE, reinterprets Turiya as a dynamic, vibrant state of known as spanda, the subtle pulsation or vibration (Cit) inherent in the supreme reality of . This tradition, synthesized by key figures such as (c. 950–1016 CE) and his disciple Kshemaraja (c. 1000–1050 CE), views Turiya not as a static transcendence but as the living throb of pure awareness that permeates and animates all existence, bridging the empirical states of waking (jagrat), dreaming (svapna), and (sushupti). In this framework, Turiya manifests as an energetic recognition of one's innate divinity, emphasizing the immanent presence of Shiva-consciousness within the practitioner. Within the Pratyabhijna school of , founded by Somananda and elaborated by Utpaladeva and , Turiya represents the pinnacle of pratyabhijna, or direct -recognition, wherein the individual soul () realizes its identity with the all-encompassing -consciousness, thereby subsuming the three lower states into a unified, non-dual . This recognition unfolds through a progressive awakening, often described in seven subtle stages of Turiya—from nijananda (self-bliss) to jagadananda (universal bliss)—each marked by intensifying vibrations of spanda that dissolve limitations and reveal the as infinite Cit. The , revealed to Vasugupta (c. 875–925 CE), foundational to this school, begin with the aphorism "Caitanyam ātmā" ( is the ) in its first , establishing Turiya as the foundational state of pure, self-luminous that underlies all manifestation. Abhinavagupta's magnum opus, the Tantraloka, further expands on Turiya by delineating four primary states of consciousness, culminating in turiya and extending to turiyatita (the state beyond Turiya), a superconscious realm where the practitioner transcends even the subtlest distinctions through total immersion in Shiva's creative energy (Shakti). Unlike the intellectual discernment (jnana) emphasized in Advaita Vedanta, realization of Turiya in Kashmir Shaivism occurs via shaktipata, the descent of divine grace from the guru or Shiva, which ignites an inner transformative process of devotion, ritual, and meditative absorption, rendering enlightenment an experiential, embodied event rather than mere philosophical insight. This approach underscores the tradition's theistic monism, where Turiya vibrates as the eternal play (krida) of Shiva and Shakti, affirming the reality of the world as a manifestation of divine freedom (svatantrya).

Yoga and Samkhya Influences

In philosophy, the concept of Turiya is implicitly aligned with , the principle of pure, unchanging that exists beyond the evolutionary processes of Prakriti, the primordial composed of the three gunas— (harmony), (activity), and tamas (inertia). The 25 , or categories of reality, describe Prakriti's manifestation into intellect (), ego (), mind (manas), senses, and elements, which collectively account for the conditioned states of waking (jagrat), dreaming (svapna), and (sushupti) as fluctuations driven by the gunas. , as the 25th , remains detached and eternal, representing the unmanifest awareness akin to Turiya, free from Prakriti's dualistic interplay and the illusory identification of with material evolution. Patanjali's Yoga Sutras, composed around 400 CE, integrate Samkhya's dualism into a practical discipline, defining in 1.2 as "yogaḥ citta-vṛtti-nirodhaḥ" (the cessation of the mind's fluctuations), culminating in as the gateway to Turiya. Here, Turiya transcends the dual forms of : savikalpa (with mental support, involving subtle cognition) and nirvikalpa (without support, marked by complete absorption where subject-object distinction dissolves), achieving the isolation () of from Prakriti. This meditative attainment aligns with Samkhya's analytical enumeration but emphasizes disciplined cessation to realize the unchanging witness consciousness beyond the three ordinary states. Later Yoga texts, such as the Yoga Vasistha, elaborate Turiya as the (natural or effortless) state, an abiding realization of non-dual awareness integrated into daily life, attainable through (breath control) and dhyana (sustained meditation) that dissolve vasanas (latent impressions). In this tradition, Turiya emerges when the practitioner transcends transient absorptions, embodying Purusha's purity amid Prakriti's flux without effortful withdrawal. Historically, and formed an atheistic, dualistic foundation that influenced Upanishadic thought, providing a rational framework for enumerating consciousness principles, though Turiya's transcendent essence was subsequently spiritualized within theistic interpretations of the scriptures. This interplay underscores how Samkhya-Yoga's emphasis on discriminative knowledge () paved the way for meditative paths to the fourth state, bridging cosmological analysis with experiential realization.

Philosophical and Practical Implications

Metaphysical Role

In Advaita Vedanta, Turiya holds the ontological status of the ground of being, identified as sat or eternal existence, which underlies all phenomena while transcending the illusory superimposition of maya. As the unchanging reality, Turiya resolves the paradox of change and permanence by positing that the transient universe arises from and dissolves into this immutable essence, akin to pots emerging from and returning to undifferentiated clay. This non-dual substratum remains unaffected by the apparent modifications of waking, dreaming, and deep sleep states, serving as the pervasive sat-chit-ananda (existence-consciousness-bliss) that constitutes the true nature of reality. Epistemologically, Turiya functions as the source of vidya or true knowledge, where self-inquiry (atma-vichara) unveils the non-dual identity of the individual self (atman) with the ultimate reality (Brahman). This realization occurs through disciplined practices such as listening to scriptures (shravanam), reflection (mananam), and contemplation (nididhyasanam), culminating in direct intuitive apprehension that dispels ignorance (avidya) and reveals the inherent unity beyond subject-object distinctions. In this state, knowledge is not acquired but recognized as the ever-present awareness, free from the limitations of empirical perception. Critiques of Turiya's non-dual framework highlight its potential to imply , where only a singular exists and other entities appear illusory, raising questions about the reality of interpersonal relations. In , this is addressed through the concept of beginningless ignorance (anadi avidya), which explains the appearance of multiplicity without compromising the unity of . counters this by stressing relational awareness within 's playful manifestation (lila), integrating dynamic interdependence to affirm the validity of perceived diversity as expressions of the divine.

Contemporary Relevance

In the 20th and 21st centuries, interpretations of Turiya have extended into modern spiritual practices, particularly through Ramana Maharshi's method of self-inquiry, which aims to access the state of pure underlying all experiences. Maharshi described self-inquiry as a direct path to realizing Turiya, the unchanging "I"-nature that transcends waking, dreaming, and states, emphasizing persistent questioning of the ego to reveal this foundational consciousness. This approach has influenced contemporary Advaita teachings, positioning Turiya as an attainable reality through introspective discipline rather than ritual alone. Neuroscience research on indicates that experienced meditators exhibit decreased connectivity in the brain's (DMN), a system linked to self-referential thinking and ego boundaries, during practices fostering present-moment . For instance, advanced induces states of "pure " where neural patterns align with non-dual experiences, suggesting empirical correlates to Turiya's transcendence of ordinary states. These findings highlight Turiya's relevance in understanding altered , though direct mappings remain interpretive. A 2025 study reported that advanced meditators experience greater non-duality during breath-watching, correlated with intrinsic neural timescales. In Western thought, Turiya resonates with transpersonal psychology, notably in Ken Wilber's integral theory, which incorporates it as the fourth state witnessing gross, subtle, and causal levels of consciousness. Wilber frames Turiya within a spectrum of developmental states, integrating Eastern non-duality with Western psychology to describe it as the ground of being that underlies personal growth and spiritual awakening. Comparisons to William James's "stream of consciousness" evoke Turiya's role as the silent observer beyond fluctuating mental contents, while echoes in Carl Jung's collective unconscious suggest a shared archetypal depth, though Jung emphasized inherited psychic structures over pure awareness. These integrations position Turiya as a bridge between Eastern metaphysics and modern psychological models. Practical applications of Turiya appear in contemporary programs and retreats, where it is framed as peak achievable through guided practices like breath-focused and self-observation. Apps such as Insight Timer and Calm incorporate elements of non-dual inspired by Turiya, promoting it as a tool for stress reduction and heightened presence amid daily life. retreats, such as those emphasizing Hridaya Yoga, teach Turiya as the fourth state to cultivate , blending traditional texts with therapeutic outcomes like emotional regulation. However, critiques highlight the of such , where Turiya's profound realization is repackaged into marketable wellness products, potentially diluting its transformative depth and fostering superficial engagement over genuine . Emerging 2020s research on psychedelics underscores gaps in traditional coverage of Turiya, linking induced to experiences of unity consciousness akin to non-dual awareness. Studies on and reveal ego dissolution and oceanic boundlessness, where participants report Turiya-like dissolution of self-other boundaries, supported by showing disrupted DMN integrity similar to meditative states. Recent 2024-2025 investigations further connect psychedelics and to and non-dual states, enhancing understanding of these experiences.
