नात्यश्नतस्तु योगोऽस्ति न चैकान्तमनश्नतः | न चातिस्वप्नशीलस्य जाग्रतो नैव चार्जुन
nātyaśnatastu yogo.asti na caikāntamanaśnataḥ . na cātisvapnaśīlasya jāgrato naiva cārjuna
然而，阿周那（Arjuna）啊，「瑜伽」（Yoga）不適用於食量過多者，亦不適用於完全不食者；不適用於習慣性睡眠過長者，當然也不適用於徹夜不眠者。
But, O Arjuna, Yoga is not for one who eats too much, nor for one who does not eat at all; neither for one who habitually sleeps too long, nor surely for one who keeps awake.
在此詩節中，主（Lord）為「瑜伽」（Yoga）學子規定了飲食。你必須在飲食和睡眠上保持節制。食量過多會使人昏昏欲睡，且會導致消化不良、脹氣以及腸肝疾病。食量過少則會導致虛弱，無法長時間靜坐冥想。你應當食量不多不少，恰好足以維持身體健康強壯所需。這也可能意味著，對於食量超過「瑜伽」經典所規定份量的人，無法在「瑜伽」上取得成功。經典規定：胃部一半應填滿食物，四分之一填滿水，剩餘四分之一應空著以便空氣自由流通。這是「瑜伽」學子的「適度飲食」（Mitahara）。
In this verse the Lord prescribes the diet for the students of Yoga. You must observe moderation in eating and sleeping. If you eat too much you will feel drowsy? and sleep will overpower you. You will get indigestion? flatulence? diseases of the bowels and the liver. If you eat too little you will get weakness and you will not be able to sit for a long time in meditation. You should eat neither more nor less than what is actually necessary for maintaining the body in a healthy and strong state.It may mean also that success in Yoga is not possible for him who eats more than the antity prescribed in the text books on Yoga. They prescribe Half the stomach must be filled with food a arter with water and the remaining fourth must be empty for the free movement of air. This is the Mitahara or moderate diest for a student of Yoga.If you sleep too much you will become lethargic. The mind will be dull and the body will be heavy. You cannot meditate. If you sleep too little you will experience drowsiness. You will sleep during meditation. Keep the golden medium. You will have rapid progress in Yoga.
