What is "vihimsa"

Vihiṃsā (Sanskrit; Tibetan phonetic: nampar tsewa) is a Buddhist term translated as "malice", "hostility", or "cruelty". It is identified as one of the twenty subsidiary unwholesome mental factors within the Mahayana Abhidharma teachings. In this context, it is defined as the category of anger ( pratigha) or aversion ( dvesha), and functions to treat others abusively and without compassion.
