In Naimiṣa, the commencement of the long sacrificial session by the seers. The arrival of Vāyu there; the question regarding the creation of the universe and related matters; the complete narration of all that by Vāyu. At the completion of the sacrificial session, the appearance of Sarasvatī from the middle of the sacrificial altar. The final ritual ablution (avabhṛthasnāna) of the seers in her as she flows in the form of a river; the question of the seers as to what caused Sarasvatī, the ornament of the realm of Brahmā, to descend from there and flow in the mortal world; the introduction to that story given by Vāyu through recounting the ancient historical account of the dispute between Brahmā and Yajña; Brahmā's conceit of supremacy upon beholding his own creation of the worlds; the dispute between Brahmā and Yajña; the appearance of Rudra there; the sprouting of a fifth head of the enraged Brahmā; the cutting off of that [head] by Rudra; the hymn of praise to Rudra made by Brahmā, and the entreaty for carrying the severed head.
