Krishna states the consequence of sama-darshana (equal vision). Those whose mind rests in equanimity have already conquered the cycle of birth and death — right here, in this life. Brahman is flawless and equal in all, and such people are established in Brahman.
A scale balanced on both sides is called steady. A person whose mind stays level through pleasure and pain, honor and insult, is free on this very earth. No future cycle binds them.
