Mbh 13.14.7e

In that foremost of asylums, which was delightful to all creatures, inhabited by many foremost of Brahmanas fully conversant with the Vedas and their branches, and by many high-souled Rishis celebrated for the difficult vows they observed, I saw, as soon as I entered, a puissant Rishi with matted locks on head and dressed in rags, who seemed to blaze forth like fire with his penances and energy. Waited upon by his disciples and possessed of tranquil soul, that foremost of Brahmanas was young in aspect. His name was Upamanyu. Unto me who bowed unto him with a nod of the head, he said,--'Welcome art thou, O thou of eyes like lotus petals. Today, by this visit of thine, we see that our penances have borne fruit. Thou art worthy of our adoration, but thou adorest us still. Thou art worthy of being seen, but thou desirest to see me.'--Joining my hands I addressed him the usual enquiries respecting the well-being of the animals and birds that resided in his asylum, of the progress of his righteousness, and of his disciples. The illustrious Upamanyu then addressed me in words that were exceedingly sweet and delightful,--'Thou shalt, O Krishna, obtain without doubt a son like unto thyself. Betaking thyself to severe penances, do thou gratify Isana, the Lord of all creatures. That divine Master, O Adhokshaja, sporteth here with his spouse by his side. O Janarddana, it was here that the deities with all the Rishis, in days of yore, gratified that foremost of deities by their penances and Brahmacharyya and truth and self-restraint, and succeeded in obtaining the fruition of many high desires. That illustrious god is verily the vast receptacle of all energies and penances. Projecting into existence and withdrawing once more unto himself all things fraught with good and evil, that inconceivable Deity whom thou seekest, O destroyer of foes, lives here with his spouse.
