Bhagavad Gita 6.16
नात्यश्नतस्तु योगोऽस्ति न चैकान्तमनश्नतः | न चातिस्वप्नशीलस्य जाग्रतो नैव चार्जुन ||
nāty-aśnatas tu yogo 'sti na caikāntam an-aśnataḥ | na cāti-svapna-śīlasya jāgrato naiva cārjuna ||
Translation
Devotion, O Arjuna! is not his 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.
Reflection
Of food, sleep, work, and stillness, which one is yours currently set too high or too low?
Read this verse in its chapter: Chapter Six
Four ways the practice fails before it begins. Too much food. No food. Too much sleep. No sleep. The man who eats heavily turns himself dull. The man who fasts hard turns himself frantic. The man who sleeps long loses the morning. The man who refuses sleep loses his judgement. Krishna names all four because each one is somebody's idea of holiness. The verse is plain. The body has to be tuned like a string, not strangled and not slack. Nothing in this paragraph is mystical. It is the practical floor under everything that comes next, and it is the floor most often skipped.
