Mbh 5.70.2a

“Sanjaya said, ‘The auspicious names (of Kesava) have been previously heard by me. Of those I will tell thee as many as I know. Kesava, however, is immeasurable, being above the power of speech to describe. He is called Vasudeva in consequence of his enveloping all creatures with the screen of illusion, or of his glorious splendour, or of his being the support and resting-place of the gods. He is called Vishnu because of his all-pervading nature. He is called Madava, O Bharata, because of his practising as a Muni, concentration of mind on truth and Yoga-absorption. He is called Madhusudana because of his having slain the Asura Madhu, and also because of his being the substance of the twenty-four objects of knowledge. Born of the Sattwata race, he is called Krishna because he uniteth in himself what are implied by the two words Krishi which signifieth “what existeth” and na which signifieth “eternal peace.” He is called Pundarikaksha from Pundarika implying his high and eternal abode, and Aksha implying “indestructible;” and he is called Janardana because he striketh fear into the hearts of all wicked beings. He is called Sattwata, because the attribute of Sattwa is never dissociated from him and also because he is never dissociated from it; and he is called Vrishabhakshana from Vrishabha implying the “Vedas” and ikshana implying “eye,” the union of the two signifying that the Vedas are his eyes, or the Vedas are the eyes through which he may be seen. That conqueror of hosts is called Aja, or “unborn,” because he hath not taken his birth from any being in the ordinary way. That Supreme Soul is called Damodara because unlike the gods his effulgence is increate and his own, and also because he hath self-control and great splendour. He is called Hrishikesa, from Hrishika meaning “eternal happiness” and Isa meaning “the six divine attributes,” the union signifying one having joy, happiness, and divinity.
