Acharya Prashant clarifies the profound meaning of 'equanimity' as described in the Uttar Gita. He explains that for common people, equanimity often mistakenly means treating two opposites as equal, such as equating success with failure or right with wrong. However, Shri Krishna’s definition of equanimity is to remain unaffected by external circumstances. It means remaining established in one's true self, the Atman, which existed before birth and remains unchanged by time. True equanimity is not about establishing equality between external objects, but about maintaining the internal state of the soul so that it does not transform into the fluctuating mind.
