Srimad Bhagvata Mahapurana: Book 10: Chapter 37: Verses 9-21
Drawing out His arm from its dead body, which resembled a (ripe) cucumber (that had burst open at several places), the mighty-armed Lord, who had killed the enemy without any effort and (therefore) stood unelated, was glorified by the highly amazed gods (lit., the denizens of heaven), who showered flowers (on Him). Approaching Sri Krsna, who was unwearied in action, Narada (the celestial sage), the foremost of the Lord's votaries, 0 protector of men, spoke to Him in secret as follows:- "0 Krsna of incomprehensible character, 0 Enchanter of all, 0 Master of Yoga (possessed of inconceivable powers), 0 Ruler of the universe, 0 Vasudeva (present in all beings), the Abode of all, the foremost of the Yadus, 0 almighty Lord ! You are the one Spirit, indwelling all created beings and remaining concealed like the fire hidden in logs of wood, nay, enshrined inside the intellect, the Witness (of all), the Supreme Person, the almighty Lord. Depending on Your own Self, You evolved the three Gunas at the dawn of creation by Your Maya (creative energy), which is (no other than) Your own Self; and with their help You create, protect and absorb (into Your own Self) this (visible) universe, unfailing of purpose and almighty as You are. As such You have descended (in the world of matter) for the annihilation of demons, goblins and ogres born as kings (lit.,the conservators of the -earth) and for the protection of the virtuous (who are the living standards of morality). Luckily enough by You, has been sportfully slain this demon (Kesi) in the form of a horse, frightened by whose neighs the gods (whose eyelids never fall) evacuated heaven.
