Sannyasa

Sannyasa (Sanskrit: संन्यास, romanized: saṃnyāsa), sometimes spelled sanyasa, is the fourth stage within the Hindu system of four life stages known as ashramas, the first three being brahmacharya (celibate student), grihastha (householder) and vanaprastha (forest dweller, retired). Sannyasa is traditionally conceptualized for men or women in the last years of their life, but young brahmacharis have the choice to skip the householder and retirement stages, renounce worldly and materialistic pursuits and dedicate their lives to spiritual pursuits.

Sannyasa, a form of asceticism marked by renunciation of material desires and prejudices, is characterized by a state of disinterest in and detachment from material life, with the purpose of spending one's life in peaceful, spiritual pursuits. An individual in Sanyasa is known as a sannyasi (male) or sannyasini (female) in Hinduism. Sannyasa shares similarities with the Sadhu and Sadhvi traditions of Jain monasticism, and the sannyasi and sannyasini share similarity with the bhikkhus and bhikkhunis of Buddhism.

Sannyasa has historically been a stage of renunciation, ahimsa (non-violence), a peaceful and simple life and spiritual pursuit in Indian traditions. However, this has not always been the case. After the invasions and establishment of Muslim rule in India, from the 12th century through the British Raj, parts of the Shaiva (Gossain) and Vaishnava (Bairagi) ascetics metamorphosed into a military order, where they developed martial arts, created military strategies, and engaged in guerrilla warfare. These warrior sanyasi (ascetics) played an important role in helping European colonial powers establish themselves in the Indian subcontinent.

Saṃnyāsa: in Sanskrit nyasa means 'purification', sannyasa means "Purification of Everything". It is a composite word of saṃ- which means "together, all", ni- which means "down" and āsa from the root as, meaning "to throw" or "to put". A literal translation of Sannyāsa is thus "to put down everything, all of it". Sannyasa is sometimes spelled as Sanyasa.

The term Saṃnyasa makes appearance in the Samhitas, Aranyakas and Brahmanas, the earliest layers of Vedic literature (2nd millennium BCE), but it is rare. It is not found in ancient Buddhist or Jaina vocabularies, and only appears in Hindu texts of the 1st millennium BCE, in the context of those who have given up ritual activity and taken up non-ritualistic spiritual pursuits discussed in the Upanishads. The term Sannyasa evolves into a rite of renunciation in ancient Sutra texts, and thereafter became a recognized, well discussed stage of life (Ashrama) by about the 3rd and 4th century CE.

Sanyasis are also known as Bhiksu, Pravrajita/Pravrajitā, Yati, Sramana and Parivrajaka in Hindu texts.

Jamison and Witzel state early Vedic texts make no mention of Sannyasa, or Ashrama system, unlike the concepts of Brahmacharin and Grihastha which they do mention. Instead, Rig Veda uses the term Antigriha (अन्तिगृह) in hymn 10.95.4, as still a part of the extended family, where older people lived in ancient India, with an outwardly role. It is in later Vedic era and over time, that Sannyasa and other new concepts emerged, while older ideas evolved and expanded. A three-stage Ashrama concept, along with Vanaprastha, emerged about or after 7th Century BC, when sages such as Yājñavalkya left their homes and roamed around as spiritual recluses and pursued their Pravrajika (wanderer) lifestyle. The explicit use of the four-stage Ashrama concept appeared a few centuries later.

However, early Vedic literature from 2nd millennium BC mentions Muni (मुनि, monks, mendicants, holy men), with characteristics that mirror those found in later Sannyasins and Sannyasinis. For example, the Rig Veda, in Book 10 Chapter 136, mentions Munis as those with Kesin (केशिन्, long haired) and Mala clothes (मल, soil-colored, yellow, orange, saffron), engaged in the affairs of Mananat (mind, meditation). The Rigveda, however, refers to these people as Muni and Vati (वति, monks who beg).
