Śāntideva (Shantideva) is an eighth century Indian Buddhist philosopher from the Mahāyāna tradition. His most famous work is the short and largely accessible Bodhicaryāvatāra (Undertaking the way to awakening or Guide to the Bodhisattva way of life). This work was an important influence on the Tibetan Buddhist tradition generally and on the current Dalai Lama in particular.
Śāntideva’s discussion of anger is in chapter 6, where, arguing against anger, he praises the virtue of patient endurance (kṣānti). He treats anger as equivalent to hatred and singles it out as the most troublesome of the three root poisons (hatred, delusion, and craving) because, more than the others, it prevents us from developing compassion.
Śāntideva makes a psychological argument against anger, pointing out that it disturbs our relationships and our peace of mind. It makes us suffer, preventing us from being happy.
