Mahabharata Anushasna Parva Chapter 158:4

Mahabharata Anushasna Parva (Dana Dharma Parva) Chapter 158:4 He is the three sacrificial fires. He is the three Vyahritis; indeed, this son of Devaki is all the gods together. He is the year; He is the Seasons; He is the Fortnights; He is the Day and the Night; He is those divisions of time which are called Kalas, and Kashthas, and Matras, and Muhurtas, and Lavas, and Kshanas. Know that this Vishwaksena is all these. The Moon and the Sun, the Planets, the Constellations, and the Stars, all the Parva days, including the day of the full moon, the conjunctions of the constellations and the seasons, have, O son of Pritha, flowed from this Krishna who is Vishwaksena. The Rudras, the Adityas, the Vasus, the Aswins, the Sadhyas, the Viswedevas, the diverse Maruts, Prajapati himself, the mother of the deities, viz., Aditi, and the seven Rishis, have all sprung from Krishna. Transforming Himself into the Wind, He scatters the universe. Of Universal form, He becomes Fire that burns all things. Changing Himself into Water, He drenches and submerges all, and assuming the form of Brahman, He creates all the diverse tribes of animate and inanimate creatures. He is Himself the Veda, yet he learns all the Vedas. He is Himself all the ordinances, yet He observes all the ordinances that have been laid down in matters connected with Righteousness and the Vedas and that force or might which rules the world. Indeed, know, O Yudhishthira, that this Kesava is all the mobile and immobile universe. He is of the form of the most resplendent light. Of universal form, this Krishna is displayed in that blazing effulgence. The original cause of the soul of all existent creatures. He at first created the waters. Afterwards He created this universe. Know that this Krishna is Vishnu. Know that He is the soul of the universe. Know that He is all the seasons; He is these diverse wonderful vegetations of Nature which we see; He is the clouds that pour rain and the lightening that flashes in the sky. He is the elephant Airavata. In fact, He is all the immobile and mobile universe. The abode of the universe and transcending all attributes, this Krishna is Vasudeva. When He becomes Jiva He comes to be called Sankarshana.
