Equanimity (Latin: æquanimitas having an even mind; aequus even animus mind/soul) is a state of psychological stability and composure which is undisturbed by experience of or exposure to emotions, pain, or other phenomena that may cause others to lose the balance of their mind. The virtue and value of equanimity is extolled and advocated by a number of major religions and ancient philosophies.
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. The Buddha described a mind filled with equanimity as "abundant, exalted, immeasurable, without hostility and without ill-will."
