we aim to optimize our emotions, we must attempt to cultivate the ancient ideal of equanimity. Equanimity is a state of undisturbed tranquility and psychological stability, with equivalent concepts in nearly every practical philosophy and religion - apatheia in Greek Stoicism, ataraxia in Epicureanism, and upekkha in Buddhism.56 Someone with this state of mind was someone whose balance of mind could not be shaken, even in the face of great adversity. Equanimity is the pinnacle of psychological robustness and control.
