नात्यश्नतस्तु योगोऽस्ति न चैकान्तमनश्नतः । न चातिस्वप्नशीलस्य जाग्रतो नैव चार्जुन

Sanskrit

हे अर्जुन ! यह योग न तो अधिक खानेवालेका और न बिलकुल न खानेवालेका तथा न अधिक सोनेवालेका और न बिलकुल न सोनेवालेका ही सिद्ध होता है।

Verily Yoga is not possible for him who eats too much, nor for him who does not eat at all, nor for him who sleeps too much, nor for him who is (always) awake, O Arjuna.

Bhagavad Gita · Chapter 6 6.16
