When Lord Viṣṇu accepted the oblations offered in the sacrifice, Dakṣa, the Prajāpati, began with great pleasure to offer respectful prayers unto Him. The Supreme Personality of Godhead is actually the master of all sacrifices and preceptor of all the Prajāpatis, and He is served even by such personalities as Nanda and Sunanda.
