Yogachara

Yogachara (Sanskrit: योगाचार, IAST: Yogācāra) is an influential tradition of Buddhist philosophy and psychology emphasizing the study of cognition, perception, and consciousness through the interior lens of meditation, as well as philosophical reasoning (hetuvidyā). Yogachara was one of the two most influential traditions of Mahayana Buddhism in India, along with Madhyamaka.

The compound Yogācāra literally means "practice of yoga", or "one whose practice is yoga", hence the name of the school is literally "the school of the yogins". Yogācāra was also variously termed Vijñānavāda (the doctrine of consciousness), Vijñaptivāda (the doctrine of ideas or percepts) or Vijñaptimātratā-vāda (the doctrine of 'mere representation'), which is also the name given to its major theory of mind which seeks to deconstruct how we perceive the world. There are several interpretations of this main theory: various forms of Idealism, as well as a phenomenology or representationalism. Aside from this, Yogācāra also developed an elaborate analysis of consciousness (vijñana) and mental phenomena (dharmas), as well as an extensive system of Buddhist spiritual practice, i.e. yoga.

The movement has been traced to the first centuries of the common era and seems to have evolved as some yogis of the Sarvāstivāda and Sautrāntika traditions in north India adopted Mahayana Buddhism. The brothers Asaṅga and Vasubandhu (both c. 4-5th century CE), are considered the classic philosophers and systematizers of this school, along with the figure of Maitreya. Yogācāra was later imported to Tibet and East Asia by figures like Shantaraksita (8th century) and Xuanzang (7th-century). Today, Yogācāra ideas and texts continue to be influential subjects of study for Tibetan Buddhism and East Asian Buddhism.

Yogācāra philosophy is primarily meant to aid in the practice of yoga and meditation and thus it also sets forth a systematic analysis of the Mahayana path of mental training (see five paths pañcamārga). Yogācārins made use of ideas from previous traditions, such as Prajñāpāramitā and the Sarvāstivāda Abhidharma tradition, to develop a novel analysis of conscious experience and a corresponding schema for Mahāyāna spiritual practice. Yogācāra sutras such as the Saṅdhinirmocana Sūtra developed various core concepts such as vijñapti-mātra, the ālaya-vijñāna (store consciousness), the turning of the basis (āśraya-parāvṛtti), the three natures (trisvabhāva), and emptiness. These form a complex system, and each can be taken as a point of departure for understanding Yogācāra.

One of the main features of Yogācāra philosophy is the concept of vijñapti-mātra. It is often used interchangeably with the term citta-mātra in modern and ancient Yogacara sources. The standard translation of both terms is "consciousness-only" or "mind-only." Several modern researchers object to this translation in favor of alternatives like representation-only. The meaning of this term is at the heart of the modern scholarly disagreement about whether Yogacara Buddhism can be said to be a form of idealism (as supported by Garfield, Hopkins, and others) or whether it is definitely not idealist (Anacker, Lusthaus, Wayman).

According to Lambert Schmithausen, the earliest surviving appearance of this term is in chapter 8 of the Saṅdhinirmocana Sūtra, which has only survived in Tibetan and Chinese translations that differ in syntax and meaning. The passage is depicted as a response by the Buddha to a question which asks "whether the images or replicas (*pratibimba) which are the object (*gocara) of meditative concentration (*samadhi), are different/separate (*bhinna) from the contemplating mind (*citta) or not." The Buddha says they are not different, "Because these images are vijñapti-mātra." The text goes on to affirm that the same is true for objects of ordinary perception.

The term is sometimes used as a synonym with citta-mātra (mere citta), which is also used as a name for the school that suggests Idealism. Schmithausen writes that the first appearance of this term is in the Pratyupanna samadhi sutra, which states "this (or: whatever belongs to this) triple world is nothing but mind (or thought: *cittamatra). Why? Because however I imagine things, that is how they appear."

Regarding existing Sanskrit sources, the term appears in the first verse of Vasubandhu's Vimśatikā (Twenty Verses), which states:
