Mbh 3.12.4a

“Arjuna said, ‘In days of old, thou, O Krishna, hadst wandered on the Gandhamadana mountains for ten thousand years as a Muni having his home where evening fell! Living upon water alone, thou hadst, in days of old, O Krishna, also dwelt for full eleven thousand years by the lake of Pushkara! And, O slayer of Madhu, with arms upraised and standing on one leg, thou hadst passed a hundred years on the high hills of Vadari,[16] living all the while upon air! And leaving aside thy upper garment, with body emaciated and looking like a bundle of veins, thou hadst lived on the banks of the Saraswati, employed in thy sacrifice extending for twelve years! And, O Krishna of mighty energy, in observance of thy vow thou hadst stood on one leg for the length of a thousand years of the celestials, on the plains of Prabhasa which it behoveth the virtuous to visit! Vyasa hath told me that thou art the cause of the creation and its course! And, O Kesava, the lord of Kshetra,[17] thou art the mover of all minds, and the beginning and end of all things! All asceticism resteth in thee, and thou too art the embodiment of all sacrifices, and the eternal one! Slaying the Asura Naraka, offspring of the Earth-first begotten, thou hadst obtained his ear-rings, and performed, O Krishna, the first horse-sacrifice (offering up that Asura as the sacrificial horse)! And, O bull of all the worlds, having performed that feat, thou hast become victorious over all! Thou hadst slain all the Daityas and Danavas mustered in battle, and giving the lord of Sachi (Indra) the sovereignty of the universe, thou hast, O Kesava of mighty arms, taken thy birth among men! O slayer of all foes, having floated on the primordial waters, thou subsequently becamest Hari,[18] and Brahma and Surya and Dharma, and Dhatri and Yama and Anala and Vasu, and Vaisravana, and Rudra, and Kala and the firmament the earth, and the ten directions!
