Mbh 7.202.4a

“‘Vyasa continued, “Hearing these words of the lotus-born Brahma, Maheswara became gratified. Desirous of extending his grace, he laughed aloud. The celestials then gratified (with praise) both Uma and Rudra. The arm of the thunder-wielding Sakra re-got its natural state. That foremost one of all the gods, that destroyer of Daksha’s sacrifice, that divine lord having the bull for his sign, became gratified with the gods. He is Rudra, he is Siva, he is Agni, he is everything, and he hath knowledge of everything. He is Indra, he is the Wind, he is the twin Aswins, and he is the lightning. He is Bhava, he is Parjanya, he is Mahadeva, he is sinless. He is the Moon, he is Isana, he is Surya, he is Varuna. He is Kala, he is Antaka, he is Mrityu, he is Yama.[274] He is the day, and he is the night. He is the fortnight, he is the month, he is the seasons. He is the morning and evening-twilights, he is the year. He is Dhatri, he is Vidhatri, he is the Soul of the universe, and he is the doer of all acts in the universe. Though himself without body, it is he who is the embodied celestial. Endued with great splendour he is adored and praised by all the gods. He is One, he is Many, he is hundred and thousand. Brahmanas versed in the Vedas say that he hath two forms. These are the terrible and the auspicious. These two forms, again, are multifarious. His auspicious forms are water, light, and the moon. Whatever is highly mysterious in the several branches of the Vedas, in the Upanishads, in the Puranas, and in those sciences that deal with the soul, is that God, viz., Maheswara, Mahadeva is even such. That God is, again, without birth. All the attributes of that God are not capable of being enumerated by me even if, O son of Pandu, I were to recite them continually for a thousand years.
