What it claims
Jainism is one of the three classical śramaṇa (renunciate) movements that arose in the eastern Gangetic plain in the sixth century BCE; the other two are Buddhism and the Ājīvika school, the latter long extinct. Its present form is associated with Vardhamāna Mahāvīra (c. 599–527 BCE), the twenty-fourth and last of a series of tīrthaṅkaras — ford-makers — that the tradition holds to extend across vast cosmic time. The metaphysics is unusual among Indic systems and worth stating precisely. The cosmos is uncreated and eternal; in it move an infinite plurality of jīvas — souls, each individually eternal, each in principle omniscient and blissful, each currently obscured. The obscuration is treated with a literalism foreign to Vedānta or to mainstream Buddhism: karma in Jain analysis is not metaphor and not mere causal residue, but a fine subtle matter that adheres to the soul through volitional action and weighs it down. Liberation (mokṣa, also kevala-jñāna) is the burning-off of the accumulated karma until the soul rises, by its own nature, to the apex of the cosmos in pure unbounded knowing.
The discipline
Because karma is held to be physical, the practice is correspondingly austere. The five great vows of the Jain monastic — mahāvratas — are ahiṃsā (non-injury), satya (truth), asteya (non-stealing), brahmacarya (celibacy) and aparigraha (non-possession). Of these, ahiṃsā is treated with a thoroughness no other Indic tradition matches. Jain ascetics sweep the path before walking, filter water to spare microorganisms, wear masks to avoid swallowing insects, and abstain from root vegetables on the basis that uprooting a plant kills it; some lineages eventually undertake santhārā, ritual fasting unto death, when the body can no longer support the disciplines. Two main monastic communities have run in parallel since roughly the third century BCE: Digambara (sky-clad), whose male ascetics renounce clothing entirely, and Śvetāmbara (white-clad), whose monastics wear simple white robes. The lay community supports the monastic and follows attenuated forms of the same vows, with vegetarianism near-universal and a long tradition of philanthropy, business ethics and animal welfare that has shaped Indian commercial life out of proportion to the community's size.
Why it isn't yet in the index
Jainism appears repeatedly in this lexicon's body prose — the ahimsa and karma entries both name it, the Hinduism account of the absorptive Indic field references it directly — and is never the subject of the rows it is referenced from. The reason is structural rather than editorial. The Jain monastic literature is largely composed in Ardhamāgadhī and Prākrit, has not been popularised in English on the scale the Buddhist or Vedāntic canons have, and the lay-facing Jain communities that have emigrated to the West tend to address an internal audience rather than producing the kind of generalist contemplative material the rest of this index catalogues. Acharya Tulsi, Acharya Mahāprajña and the Anuvrat movement of the twentieth century are the most visible recent attempts to articulate the tradition for a wider readership; they have not yet produced an English-language teacher of the public stature of a Thich Nhat Hanh or a Rupert Spira. The entry exists here to acknowledge the gap and to make the cross-referencing in adjacent entries land somewhere rather than nowhere.
What it isn't
Jainism is not a sect of Hinduism — the absorptive habits of the Hindu field have repeatedly tried to read it that way, and the Jain tradition has resisted with care for two and a half millennia. It does not accept Vedic authority, does not posit a creator deity, does not work with a single eternal Brahman underlying experience, and treats the soul-plurality of its metaphysics as load-bearing in a way that Vedāntic non-dualism would dissolve. It is also not a variant of Buddhism, though the two traditions arose in the same milieu and share much vocabulary. Where the Buddha analysed experience into anātman — no-self — Mahāvīra analysed it into a plurality of eternal selves; where Buddhist karma is read as causal residue subject to skilful redirection, Jain karma is a subtle physical accretion to be burned off; where Buddhist ahiṃsā is graded by intention, Jain ahiṃsā is graded by injury produced and is uncompromising about the injury. And it is not the popular Western image of pacifism — the Jain monastic tradition is one of the most disciplined contemplative regimes any culture has produced, and the practice is active asceticism rather than ethical opinion.
