The awakened sages call a person wise when all his undertakings are free from anxiety about results; all his selfish desires have been consumed in the fire of knowledge. The wise, ever satisfied, have abandoned all external supports. Their security is unaffected by the results of their action; even while acting, they really do nothing at all. Free from expectations and from all sense of possession, with mind and body firmly controlled by the Self, they do not incur sin by the performance of physical action.
Bhagavad Gita 4:19-21
