What is "pratigha"

Pratigha (Sanskrit; Pali: paṭigha; Tibetan Wylie: khong khro) is a Buddhist term that is translated as "anger". It is defined as a hostile attitude towards sentient beings, towards frustration, and towards that which gives rise to one's frustrations; it functions as a basis for faultfinding, for negative actions, and for not finding a moment of peace or happiness.

Pratigha is identified as:

• One of the six root unwholesome mental factors within the Mahayana Abhidharma tradition
• One of the ten fetters in the Theravada tradition (according to the Dhammasangani)
