Mbh 1.227.2c

With this weapon, without doubt, thou shalt be superior in battle to men and gods, and Rakshasas and Pisachas, and Daityas and Nagas. And thou shalt certainly be able with this to smite all. And, O Madhava, hurled by thee in battle at thy foes, this weapon will irresistibly slay the enemy and again come back into thy hands.’ And the lord Varuna, after this, gave unto Krishna a mace, of name Kaumodaki, capable of slaying every Daitya and producing, when hurled, a roar like that of the thunder. Then Arjuna and Achyuta, filled with joy said unto Pavaka, ‘O exalted one, furnished with weapons and knowing their use, possessed of cars with flags and flagstaffs, we are now able to fight with even all the celestials and the Asuras (together), let alone the wielder of the thunderbolt desirous of fighting for the sake of the Naga (his friend Takshaka).’ Arjuna also said, ‘O Pavaka, while Hrishikesa, endued with abundant energy, moves on the field of battle with this discus in hand, there is nothing in the three worlds that he will not be able to consume by hurling this weapon. Having obtained the bow Gandiva and this couple of inexhaustible quivers I also am ready to conquer in battle the three worlds. Therefore, O lord, blaze thou forth as thou likest, surrounding this large forest on every side. We are quite able to help thee.’
