In the Krita age of that ancient Kalpa, Rudra, devoted to Yoga, O monarch, communicated it to all those Rishis that are known by the name of Valikhilyas. Through the illusion of Narayana, it once more disappeared from the universe. In the third birth of Brahma, which was due to the speech of Narayana, this religion once more sprang up, O king, from Narayana himself. Then a Rishi of the name of Suparna obtained it from that foremost of Beings. The Rishi Suparna used to recite this excellent religion, this foremost of cults, three times during the day. In consequence of this, it came to be called by the name of Trisauparna in the world. This religion has been referred to in the Rigveda. The duties it inculcates are exceedingly difficult of observance. From the Rishi Suparna, this eternal religion was obtained, O foremost of men, by the God of wind, that sustainer of the lives of all creatures in the universe. The God of wind communicated it unto such Rishis as subsist upon what remains of sacrificial offerings after feeding guests and others. From those Rishis this excellent religion was obtained by the Great Ocean. It once more disappeared from the universe and became merged into Narayana. In the next birth of the high-souled Brahman when he sprang from the ear of Narayana, listen, O chief of men, to what happened in that Kalpa. The illustrious Narayana, otherwise called Hari, when he resolved upon Creation, thought of a Being who would be puissant enough to create the universe. While thinking of this, a Being sprang from his ears competent to create the universe. The Lord of all called him by the name of Brahma. Addressing Brahma, the Supreme Narayana said unto him,--"Do thou, O son, create all kinds of creatures from thy mouth and feet. O thou of excellent vows, I shall do what will be beneficial for thee, for I shall impart to thee both energy and strength sufficient to render thee competent for this task.
