an established, strictly observed rule. Rishabhanatha (Ādinātha), the first Jain Tirthankara, whom modern Western historians consider to be a historical figure, followed by Parshvanatha (Pārśvanātha) the twenty-third Tirthankara lived in about the 9th century BCE. He founded the community to which Mahavira's parents belonged. Ahimsa was already part of the "Fourfold Restraint" (Caujjama), the vows taken by Parshva's followers. In the times of Mahavira and in the following centuries, Jains were at odds with both Buddhists and followers of the Vedic religion or Hindus, whom they accused of negligence and inconsistency in the implementation of Ahimsa. According to the Jain tradition either lacto vegetarianism or veganism is prescribed. The Jain concept of Ahimsa is characterised by several aspects. Killing of animals for food is absolutely ruled out. Jains also make considerable efforts not to injure plants in everyday life as far as possible. Though they admit that plants must be destroyed for the sake of food, they accept such violence only inasmuch as it is indispensable for human survival, and there are special instructions for preventing unnecessary violence against plants. Jain monks and nuns go out of their way so as not to hurt even small insects and other minuscule animals. Both the renouncers and the laypeople of Jain faith reject meat, fish, alcohol and honey as these are believed to harm large or minuscule life forms. Jaina scholars have debated the potential injury to other life forms during one's occupation. Certain Jain texts, states Padmannabh Jaini – a Jainism scholar, forbid people of its faith from husbandry, agriculture and trade in animal-derived products. Some Jains abstain from farming because it inevitably entails unintentional killing or injuring of many small animals, such as worms and insects, These teachings, in part, have led the Jain community to focus on trade, merchant, clerical and administrative occupations to minimize arambhaja-himsa (occupational violence against all life forms). For the layperson, the teaching has been of ahimsa with pramada – that is, reducing violence through proper intention and being careful in every action on a daily basis to minimize violence to all life forms. The Jain texts, unlike most Hindu and Buddhist texts on just war, have been inconsistent. For its monastic community – sadhu and sadhvi – the historically accepted practice has been to "willingly sacrifice one's own life" to the attacker, to not retaliate, so that the mendicant may keep the First Great
