Mahabharata Anushasna Parva Chapter 158:2

Mahabharata Anushasna Parva (Dana Dharma Parva) Chapter 158:2 When the cause of Righteousness languishes, this Krishna takes birth in the race of either the gods or among men. Staying on Righteousness, this Krishna of cleansed soul (on such occasion) protects both the higher and the lower worlds. Sparing those that deserve to be spared, Krishna sets himself to the slaughter of the Asura, O Partha! It is he who is all acts proper and improper and it is he who is the cause. It is Krishna who is the act done, the act to be done, and the act that is being done. Know that that illustrious one is Rahu and Soma and Sakra. It is he that is Viswakarma. It is he that is of universal form. He is the destroyer and he is the Creator of the universe. He is the wielder of the Sula (lance); He is of human form; and He is of terrible form. All creatures sing his praises, for he is known by his acts. Hundreds of Gandharvas and Apsaras and deities always accompany him. The very Rakshasas hymn his praise. He is the Enhancer of Wealth; He is the one victorious Being in the universe. In Sacrifices, eloquent men hymn His praises. The singers of Samans praise Him by reciting the Rathantaras. The Brahmanas praise Him with Vedic Mantras. It is unto Him that the sacrificial priests pour their libations. The deities with Indra at their head hymned His praise when He lifted up the Gobardhana mountains for protecting the cow-herds of Brindavana against the incessant showers that Indra poured in rage. He is, O Bharata, the one Blessing unto all creatures. He, O Bharata, having entered the old Brahma cave, beheld from that place the original cover of the world in the beginning of Time.[] Agitating all the Danavas and the Asuras, this Krishna of foremost feats rescued the earth. It is unto Him that people dedicate diverse kinds of food. It is unto Him that the warriors dedicate all kinds of their vehicles at the time of war. He is eternal, and it is under that illustrious one that the welkin, earth, heaven, all things exist and stay. He it is who has caused the vital seed of the gods Mitra and Varuna to fall within a jar, whence sprang the Rishi known by the name of Vasishtha. It is Krishna who is the god of wind; it is He who is the puissant Aswins; it is He who is that first of gods, viz., the sun possessed of a thousand rays. It is He by whom the Asuras have been subjugated. It is He who covered the three worlds with three steps of His. He is the soul of the deities and human beings, and Pitris. It is He who is the Sacrifice performed by those persons that are conversant with the rituals of sacrifices. It is He who rises every day in the firmament (in the form of the sun) and divides Time into day and night, and courses for half the year northwards and for half the year southwards. Innumerable rays of light emanate from Him upwards and downwards and transversely and illumine the earth. Brahmanas conversant with the Vedas adore Him. Taking a portion of His rays the sun shines in the firmament.
