Dvesha

Dvesha is a Buddhist and Hindu term that is translated as "hate, aversion". In Hinduism, it is one of the Five Poisons or kleshas.
Walpola Rahula renders it as "hatred", as does Chogyam Trungpa.

In Buddhism

In Buddhism, Dvesha is the opposite of raga. Along with Raga and Moha, Dvesha is one of the three character afflictions that, in part, cause Dukkha. It is also one of the "threefold fires" in Buddhist Pali canon that must be quenched.
Dvesha is symbolically present as the snake in the center of Tibetan bhavachakra drawings.
Dvesha is identified in the following contexts within the Buddhist teachings:

One of the three poisons within the Mahayana Buddhist tradition.
One of the three unwholesome roots within the Theravada Buddhist tradition
One of the fourteen unwholesome mental factors within the Theravada Abhidharma teachings

In Hinduism

Yoga Sutras II.8 describes dvesha as originating from encounters with pain. In his commentary, Vyasa explains that aversion manifests as resistance, anger, frustration, or resentment toward anything associated with past painful experiences. Aversion is also closely related to attachment, as both are rooted in past experiences.
