Satya is not simply not lying. The vow covers false speech, and the commentaries extend it to speech that is harsh, that betrays confidence, that spreads what one has not verified, and to false writing and false testimony. The famous hard case in the literature is the ascetic who sees a hunted animal flee and is asked by the hunter where it went: telling the truth causes death, lying breaks the vow. The classical resolution is that ahimsa is the highest vow and the others exist in service of it, and that the correct response is silence — an answer the texts themselves acknowledge is not always available, and one that has been argued about for centuries. Mahavira's own instruction on speech, in the Acharanga, is that one should speak only after considering; monastics additionally renounce vikatha, idle talk about food, politics, women and kings, which is a substantial share of ordinary conversation. The muhpatti, the cloth held or tied over the mouth by many Svetambara mendicants, is nominally about airborne organisms and functions equally as a constant physical reminder about speech.
