Mahabharata Anushasna Parva Chapter 160:3

Mahabharata Anushasna Parva (Dana Dharma Parva) Chapter 160:3 The child, however, paralysed the arm, looking like a mace of iron, of Indra with the thunderbolt in it. The deities all became stupefied, and they could not understand that the child was the Lord of universe. Verily, all of them along with the very Regents of the world, found their intellects stupefied in the matter of that child who was none else than the Supreme Being. Then the illustrious Grandsire Brahma, reflecting with the aid of his penances, found out that that child was the foremost of all Beings, the lord of Uma, Mahadeva of immeasurable prowess. He then praised the Lord. The deities also began to hymn the praises of both Uma and Rudra. The arm (which had been paralysed) of the slayer of Vala then became restored to its former state. The Mahadeva, taking birth as the Brahmana Durvasa of great energy, resided for a long time at Dwaravati in my house. While residing in my abode he did diverse acts of mischief. Though difficult of being borne, I bore them yet from magnanimity of heart. He is Rudra; he is Shiva; he is Agni; he is Sarva; he is the vanquisher of all; he is Indra, and Vayu, and the Aswins and the god of lightning. He is Chandramas; he is Isana; he is Surya; he is Varuna; he is Time; he is the Destroyer; he is Death; he is the Day and the Night; he is the fortnight; he is the seasons; he is the two twilights; he is the year. He is Dhatri and he is Vidhatri; and he is Viswakarma; and he is conversant with all things. He is the cardinal points of the compass and the subsidiary points also. Of universal form, he is of immeasurable soul. The holy and illustrious Durvasa is of the complexion of the celestials. He sometimes manifests himself singly; sometimes divides himself into two portions; and sometimes exhibits himself in many, a hundred thousand forms. Even such is Mahadeva. He is, again, that god who is unborn. In even a hundred years one cannot exhaust his merits by reciting them.
