Devotion is not his, O Arguna! who eats too much, nor his who eats not at all; not his who is addicted to too much sleep, nor his who is (ever) awake. That devotion which destroys (all) misery is his, who takes due food and exercise, who toils duly in all works, and who sleeps and awakes (in) due (time). When (a man's) mind well restrained becomes steady upon the self alone, then he being indifferent to all objects of desire, is said to be devoted.
