Equanimity vs composure
Composure is the outward maintenance of calm — the steady voice, the controlled expression, the absence of visible distress. Equanimity is the inner evenness of mind that makes genuine composure possible. Composure can be performed through effort; equanimity is harder to fake. You maintain composure; you cultivate equanimity.
