The practice of tapas by Dharma and Yajña wishing to become Rudra’s mount; the vision of Rudra. The praise of Rudra offered by Dharma and Yajña. Their supplication to attain the status of Rudra’s mount even in another birth, and the attainment of the desired boon. Surabhi’s practice of tapas to obtain an peerless son. The birth of the bull from Surabhi; the birth of the eleven Rudras; the birth of the cow-maidens (the birth of the seven cows). The narration of the deeds of the bull; the thirsty bull, having grazed on grass, beginning to drink water in the ocean; the subjugation of the bull by the submarine fire fearing the drying up of the ocean. The vomiting up of the drunk water without remainder; the worship of Rudra by the bull thus humiliated. The subjugation of the submarine fire by the pleased Rudra at the bull’s prayer, and its subsequent release. The creation by Rudra, at the prayer of the deities, of the gaṇa named Prabhākara to restrain the bull’s velocity that distressed the worlds. Rudra’s taking the bull as his mount; the bull’s embodiment of all the gods; the account of the presence of all beings in the parts of his body.
