For one who eats too much, who eats beyond the measure of food suited to himself, there is no yoga; and for one who does not eat at all there is no yoga, by the scripture 'food in the measure suited to oneself protects and does not harm; what is in excess harms, and food that is too little does not protect'. So the yogin should not eat more or less than the food suited to himself. Or else: for the yogin who eats beyond the measure of food laid down in the yoga treatise, there is no yoga. The measure is stated thus: 'let him fill two parts with food including its garnish, the third with water, and leave the fourth for the movement of air'. Likewise, yoga does not come to one given to too much sleep, nor to one who keeps awake too much, O Arjuna. How, then, does yoga come about? He says.
