नात्यश्नतस्तु योगोऽस्ति न चैकान्तमनश्नतः।
न चातिस्वप्नशीलस्य जाग्रतो नैव चार्जुन।।6.16।।
।।6.16।।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।
The regulations regarding the eating of food and the regimen of sleep that are to be followed by those practising yoga or the science of the individual consciousness attaining communion with the ultimate consciousness are now being given by Lord Krishna. By not following these injunctions it is not possible to even commence practising any form of yoga.
Abstention from performing regulatory fasting such as Ekadasi which is the 11th day of the waxing or waning moon is sanctioned only for the weak and invalid. In the Narada Purana it states: That one who is strong having given up sleep, food, fear, lethargy and actions, meditates within on the Supreme Lord Krishna or His authorised incarnations with eyes half-closed focused on the tip of the nose or the space between the eyebrows attains equanimity of mind.
There is no commentary for this verse.
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.
