Mbh 5.70.2b

He is called Mahavahu, because he upholdeth the earth and the sky with his two arms. He is called Adhakshaja, because he never falleth down or suffereth any deterioration, and is called Narayana from his being the refuge of all human beings. He is called Purusottama from Puru implying “he that createth and preserveth” and so meaning “he that destroyeth, the union signifying one that createth, preserveth, and destroyeth the universe”. He possesseth a knowledge of all things, and, therefore, is called Sarva. Krishna is always in Truth and Truth is always in him, and Govinda is Truth’s Truth. Therefore, he is called Satya. He is called Vishnu because of his prowess, and Jishnu because of his success. He is called Ananta from his eternity, and Govinda from his knowledge of speech of every kind. He maketh the unreal appear as real and thereby beguileth all creatures. Possessed of such attributes, ever devoted to righteousness, and endued with divinity, the slayer of Madhu, that mighty-armed one incapable of decay, will come hither for preventing the slaughter of the Kurus.’”
