Jainism and ahimsa

Of all the traditions invoked in vegan histories, Jainism is the one that most fully anticipates the modern ethic. Its central commitment, ahimsa — non-harm to all living beings — is older than the Buddha, older than Pythagoras, and has been continuously practised by an identifiable community for roughly twenty-five centuries. Jain laity have kept a strict vegetarian table since antiquity, and a growing movement within the community now treats veganism as the logical extension of the same vow.

Mahavira and the twenty-four tirthankaras

Jains do not regard their tradition as founded by any single teacher. The Jain timeline is structured by twenty-four tirthankaras — literally “ford-makers,” those who build a crossing over the river of rebirth. The twenty-third, Parshvanatha, is plausibly a historical figure of the ninth or eighth century BCE, associated with four vows: non-violence, truthfulness, non-stealing, and non-possession. The twenty-fourth and last of the current cosmic cycle is Vardhamana, known by the epithet Mahavira (“great hero”), traditionally dated around 599 to 527 BCE, though some scholars prefer a later fifth-century chronology. Mahavira added brahmacharya (celibacy or sexual restraint) to Parshvanatha’s four, producing the five great vows of Jain mendicancy as they have been transmitted since (Jaini 1979; Chapple 1993).

Ahimsa is the first of the five, and the Jain canon is explicit that the others are derivative. The Acharanga Sutra, first of the angas of the Svetambara canon and widely regarded as preserving some of the oldest Jain material, opens with a long meditation on the sentience of water, fire, earth, air, plants, and mobile creatures. “All breathing, existing, living, sentient creatures should not be slain, nor treated with violence, nor abused, nor tormented, nor driven away. This is the pure, unchangeable, eternal law” (Jacobi trans., 1884).

Graded respect for life

Jain cosmology does not draw a sharp human-animal boundary. It draws a great many boundaries, ordered by the number of senses a being possesses. At the base sit the sthavara or immobile beings — ekendriya, one-sensed — comprising earth-bodied, water-bodied, fire-bodied, air-bodied, and plant-bodied organisms, each understood as living but lacking mobility and the other senses. Above them rise the trasa or mobile beings: two-sensed (worms, molluscs), three-sensed (ants, lice), four-sensed (flies, bees), and five-sensed (fish, birds, mammals, humans, and certain celestial and hell beings). The Tattvartha Sutra of Umasvati, the earliest systematic philosophical text accepted by both Svetambara and Digambara sects, sets this hierarchy out in book two and grounds the Jain calculus of harm in it (Umasvati, That Which Is, trans. Tatia, 1994).

The ethical implication is not that lower beings may be harmed freely but that the severity of karmic injury scales with the sensory and mental capacities of the victim. Killing a five-sensed animal incurs heavier karma than killing a worm; killing a worm is heavier than uprooting a plant; uprooting a plant is heavier than disturbing water or soil. Because no embodied action is harm-free, the lay Jain aim is graded minimization rather than elimination. Monastics push the gradient further: the muhpatti mouth-covering worn by Svetambara monks and nuns filters airborne microorganisms, the peacock-feather pinchi of Digambara monks sweeps a path clear of insects, and drinking water is traditionally filtered and boiled to reduce harm to water-bodied life.

Diet: what Jains do and do not eat

The lay Jain diet, followed by the roughly four to five million Jains in India and a global diaspora, excludes all meat, fish, and eggs, and for observant households excludes honey and alcohol as well. The reasoning is uniform: these foods directly involve killing or exploiting mobile beings.

The distinctive Jain restriction is on root vegetables. Potatoes, onions, garlic, carrots, ginger, turmeric (in fresh root form), radishes, and beets are avoided by strictly observant Jains, and entirely forbidden during the Paryushana and Das Lakshana festivals and among Digambara and Sthanakvasi ascetics. The rationale given in Jaini’s Jaina Path of Purification combines several considerations: uprooting a plant kills the whole organism rather than harvesting a fruit or leaf; root vegetables are often home to colonies of microorganisms; and certain bulbs are regarded as ananta-kaya, host-bodies for infinite one-sensed souls. Fermented foods, overripe fruit, and food kept overnight are similarly restricted under the principle of abhakshya (the uneatable), since decomposition produces new microbial life that ingestion would destroy.

Fruits, grains, pulses, nuts, leafy vegetables harvested without killing the plant, and dairy have historically constituted the core. Dairy was long treated as ahimsic on the assumption that milk was given freely by contented cows in village economies where calves were not separated at birth and cows were not slaughtered at the end of their productive lives. That assumption is exactly what has collapsed.

The contemporary Jain vegan turn

From the late twentieth century onward, a reform movement inside the Jain community has argued that commercial dairy production is incompatible with the first vow. Industrial milk, whether in India, North America, or Europe, entails the forced insemination of cows, the removal of calves shortly after birth, the slaughter of male calves and spent dairy cows, and living conditions that many Jain teachers find impossible to square with ahimsa. Chapple (1993) documented the early debates; Waldau and Patton’s A Communion of Subjects (2006) includes chapters tracing the reform arguments through the 1990s.

The organizational shape of the movement is now well developed. Jain Vegans, a UK network founded in 2001, publishes position papers, runs educational events, and maintains lists of endorsing acharyas and scholars. Young Jains (UK) has formally adopted veganism as its recommended dietary practice and campaigned for vegan offerings at Jain community events and temple bhojanshalas. In North America, the Federation of JAINA passed resolutions in the 2010s urging members to move toward a vegan lifestyle, and the Los Angeles Jain Center installed plant-milk service at its cafeteria. Donaldson and Kymlicka, in their comparative work on dharmic animal ethics, treat Jainism as the tradition most institutionally ready to undertake the shift, because its own internal logic already supplies the argument (Donaldson and Kymlicka 2020).

Resistance persists. Older generations cite long-standing ritual uses of ghee, milk offerings in puja, and the cultural centrality of dairy in Gujarati and Rajasthani cuisines, the regional heartlands of Jainism. Reformers reply that ritual substitutes — almond milk in abhisheka, plant oils in lamps — preserve the form of practice while honouring its meaning. The argument inside Jainism is recognizably similar to the argument that split the Vegan Society from the Vegetarian Society in 1944, and indeed the Jain reformers often cite Donald Watson and H. Jay Dinshah, as Western vegans in turn cite Mahavira.

Why this lineage matters

Jain ahimsa is not a prototype of veganism in the sense of being an earlier version of the same thing. Its cosmology, karma metaphysics, and graded ontology of souls are distinct from anything in the European ethical tradition. But it is the longest continuous demonstration that a human community can organize its eating, clothing, and economic life around the principle of minimum harm to other sentient beings, and that the principle can survive two and a half millennia of political change. When contemporary vegans reach for evidence that the ethic is not a late modern eccentricity, Jainism is the best evidence they have.

The reform turn inside the community, from strict lacto-vegetarianism toward full veganism, suggests that the logic of ahimsa, worked out honestly against the conditions of industrial animal agriculture, arrives at the same destination from the East as it does from the West. The tradition that taught the first vow is now, in its most reflective institutions, taking the vow one step further.
