“[Lord Kṛṣṇa said:] ‘My dear Arjuna, one cannot perform mystic yoga if he eats more than necessary or needlessly fasts, sleeps and dreams too much or does not sleep enough. One should eat and enjoy his senses as much as necessary, one should properly endeavor to execute his duties, and one should regulate his sleep and wakefulness. Thus one can become freed from material pains by executing mystic yoga.’”
