- 1: evenness of mind especially under stress <nothing could disturb his equanimity>
- 2: right disposition : balance <physical equanimity>
- In Hinduism, equanimity is the concept of balance and centeredness which endures through all possible changes in circumstances. According to the Bhagavad Gītā, one may achieve equanimity through meditation.
- In Buddhism, equanimity (upekkhā, upekṣhā) is one of the four immeasurables
Neither a thought nor an emotion, it is rather the steady conscious realization of reality's transience. It is the ground for wisdom and freedom and the protector of compassion and love. While some may think of equanimity as dry neutrality or cool aloofness, mature equanimity produces a radiance and warmth of being."
- Equanimity (upekṣhā) is also mentioned in Patañjali's Yoga Sutras (1.33), as one of the four sublime attitudes, along with loving-kindness (maitri), compassion (karuṇā), and joy (mudita). This list is identical to the four immeasurables in Buddhist literature. The Upeksha Yoga school foregrounds equanimity as the most important tenet of a yoga practice.
- Apatheia (Greek: ἀπάθεια) in Stoic philosophy refers to a state of mind where one is free from emotional disturbance. This might be translated as equanimity or indifference. This is the root of the word apathy. Apatheia must, however, not be confused with apathy. Apatheia is a positive term; apathy, a purely negative one.
- The word "Islam" is derived from the Arabic word Aslama, which denotes the peace that comes from total surrender and acceptance. Being a Muslim can therefore be understood to mean that one is in a state of equanimity.
