Mbh 12.343.6

"'The blessed and holy one[1880] continued. "Having mutually caused such marks on each other's person, the two Rishis Nara and Narayana thus made friends with Rudra, and dismissing the deities, once more set themselves to the practice of penances with a tranquil soul. I have thus told thee, O son of Pritha, how in that battle which took place in days of yore between Rudra and Narayana, the latter got the victory. I have also told thee the many secret names by which Narayana is called and what the significations are, O Bharata, of one of those names, which, as I have told thee, the Rishis have bestowed upon the great God. In this way, O son of Kunti, assuming diverse forms do I rove at will through the Earth, the region of Brahma himself, and that other high and eternal region of felicity called Goloka. Protected by me in the great battle, thou hast won a great victory. That Being whom, at the time of all thy battles, thou beheldest stalking in thy van, know, O son of Kunti, is no other than Rudra, that god of gods, otherwise called by the name of Kaparddin. He is otherwise known by the name of Kala,[1881] and should be known as one that has sprung from my wrath. Those foes whom thou hast slain were all, in the first instance, slain by him.[1882] Do thou bend thy head unto that god of gods, that lord of Uma, endued with immeasurable puissance. With concentrated soul, do thou bend thy head unto that illustrious Lord of the universe, that indestructible deity, otherwise called by the name of Hari. He is none else than that deity who, as I have repeatedly told thee, has sprung from my wrath. Thou hast, before this, heard, O Dhananjaya, of the puissance and energy that reside in him!"'"
