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. 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.
