Mbh 5.48.2i

The person whose success is only wished for by Krishna, without the latter’s actually taking up arms in his behalf, is certain to prevail over all enemies, even if those be the celestials with Indra at their head, while anxiety there is none if they be human. He that wisheth to conquer in battle that foremost of heroes, Vasudeva’s son Krishna endued with great energy, wisheth to cross by his two arms alone the great ocean of wide expanse and immeasurable water. He that wisheth to split by a slap of his palm the high Kailasa mountain, is not able to do the slightest damage to the mountain although his hand only with its nails is sure to wear away. He that would conquer Vasudeva in battle, would, with his two arms, extinguish a blazing fire, stop the Sun and the Moon, and plunder by force the Amrita of the gods,--that Vasudeva, viz., who having mowed down in battle by main force all the royal warriors of the Bhoja race, had carried off on a single car Rukmini of great fame for making her his wife; and by her was afterwards born Pradyumna of high soul. It was this favourite of the gods, who, having speedily smashed the Gandharas and conquered all the sons of Nagnajit, forcibly liberated from confinement king Sudarsana of great energy. It was he that slew king Pandya by striking his breast against his, and moved down the Kalingas in battle. Burnt by him, the city of Varanasi remained for many years without a king, incapable of being defeated by others. Ekalavya, the king of the Nishadas, always used to challenge this one to battle; but slain by Krishna he lay dead like the Asura Jambha violently thrashed on a hillock. It was Krishna, who, having Baladeva for his second, slew Ugrasena’s wicked son (Kansa), seated in court in the midst of the Vrishnis and the Andhakas, and then gave unto Ugrasena the kingdom.
