Verse
नात्यश्नतस्तु योगोऽस्ति न चैकान्तमनश्नतः ।न चातिस्वप्नशीलस्य जाग्रतो नैव चार्जुन ॥
nātyaśnatastu yogo’sti na caikāntamanaśnataḥna cātisvapnaśīlasya jāgrato naiva cārjuna
Verily this Yoga is not for him who eats too much or sleeps too much, even as it is not for him who gives up sleep and food, O Arjuna.
Gītā 6·16
