No one can remain inactive even for a moment; being forced to act by the very qualities of Nature.
The wise man sees inactivity in action and action in inactivity; he is a yogi who performs all actions.
Finding satisfaction in individual actions (dharma) the man can achieve perfection.
Perform your action, Arjuna, with feeling and attitude of yogi. Cast away attachment and be neutral to success or failure. Yoga is forbearance.
