who preached about ahimsa

The excerpts from the Acharanga Sutra and other texts in the provided context primarily focus on monastic rules, conduct, and philosophical terms but do not specifically identify the individual who preached ahimsa. Jain philosophy traditionally attributes the preaching of ahimsa most prominently to Lord Mahavira, the 24th Tirthankara, who emphasized non-violence as a core ethical principle. However, this specific information is not present in the given texts.

The Acharanga Sutra, one of the oldest Jain scriptures, discusses various vows and disciplines for monks, including aspects related to non-violence, but the context here does not directly state the preacher of ahimsa. Similarly, other texts cited do not provide a direct reference to the originator or preacher of ahimsa.

Therefore, based solely on the provided context, it is not possible to definitively state who preached about ahimsa.
