sa vai rudraḥ sa ca śivaḥ so'gniḥ śarvaḥ sa sarvavit |
sa cendraścaiva vāyuśca so'śvinau sa ca vidyutaḥ || 65 ||

"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 lighting. 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. 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.
