BG 6.16
नात्यश्नतस्तु योगोऽस्ति न चैकान्तमनश्नतः
न चाति स्वप्नशीलस्य जाग्रतो नैव चार्जुन
nātyaśnatastu yogo'sti na caikāntamanaśnataḥ
na cāti svapnaśīlasya jāgrato naiva cārjuna
TRANSLATION
Yoga is not for him who over-eats, nor for him who fasts excessively; not for him, O Arjuna, who sleeps too much, nor for him who stays awake too long.
PURPORT
Over-eating and excessive fasting are opposed to Yoga. So also are excessive recreation and non-recreation, too much of sleep and too much of vigil. So too, are overwork and idleness.
