अहं वैश्वानरो भूत्वा प्राणिनां देहमाश्रितः।
प्राणापानसमायुक्तः पचाम्यन्नं चतुर्विधम्।।15.14।।
15.14 Taking the form of Vaisvanara and residing in the bodies of creatures, I, in association with Prana and Apana, digest the four kinds of food.
15.14 Becoming the digestive fire, or the fire of digestion, I function within the bodies of all living creatures. In union with various activities of inward and outward breaths, I digest the four kinds of food eaten by individuals. These consist of foods to be chewed, sucked, licked and drunk. The Supreme Person who has the Soma, digestive fire etc., as his glory (Vibhuti) is here eated with Him by means of co-ordinate predication in the verses Becoming the juicy Soma and Becoming the digestive fire. He now sets forth the reason for eating these glories with Himself.
