न चातिस्वप्नशीलस्य जाग्रतो नैव चार्जुन।।6.16।।
।।6.16।। परन्तु हे अर्जुन यह योग उस पुरुष के लिए सम्भव नहीं होता जो अधिक खाने वाला है या बिल्कुल न खाने वाला है तथा जो अधिक सोने वाला है या सदा जागने वाला है।।
After describing the results of meditation Lord Krishna gives the regulations regarding the eating of food and the regimen of sleep habits. One who eats like a glutton or sleeps like a sloth as well as one who fasts too much and sleeps to little are never qualified to practise yoga or the science of the individual consciousness attaining communion with the ultimate consciousness. In regard to food it is described by Pantajali that the stomach should be filled one-half with food, one-quarter with liquid and one-quarter should be kept free for the movement of air.
