Upanāha (Sanskrit; Tibetan phonetic: khön du dzinpa) is a Buddhist term translated as "resentment" or "enmity". It is defined as clinging to an intention to cause harm, and withholding forgiveness.Guenther (1975), Kindle Locations 874-875.Kunsang (2004), p. 27. It is one of the twenty subsidiary unwholesome mental factors within the Mahayana Abhidharma teachings.
The Abhidharma-samuccaya states:
What is resentment? It is not letting go of an obsession which develops through association with the anger which underlies it. Its function is to be the basis of non-endurance.
Alan Wallace described upanāha as "a lingering holding of anger (Sanskrit: krodha)".
