Bhagavad Gita

“We must act in a selfless spirit, Krishna says, without ego-involvement and without getting entangled in whether things work out the way we want; only then will we not fall into the terrible net of karma. We cannot hope to escape karma by refraining from our duties: even to survive in the world, we must act.”
― Krishna-Dwaipayana Vyasa, The Bhagavad Gita
