Worshipping, by (the performance of) his own duty, him from whom all things proceed, and by whom all this is permeated, a man obtains perfection. One's duty, though defective, is better than another's duty well performed. Performing the duty prescribed by nature, one does not incur sin. O son of Kunti! one should not abandon a natural duty though tainted with evil; for all actions are enveloped by evil, as fire by smoke.
