Mbh 13.19.6a

"'Bhishma continued, "The illustrious Ashtavakra set out on his journey. He proceeded more and more towards the north and at last reached the Himavat mountains peopled by Siddhas and Charanas.[191] Arrived at the Himavat mountains, that foremost of Brahmanas then came upon the sacred river Vahuda whose waters produce great merit. He bathed in one of the delightful Tirthas of that river, which was free from mud, and gratified the deities with oblations of water. His ablutions being over, he spread a quantity of Kusa grass and laid himself down upon it for resting awhile at his ease.[192] Passing the night in this way, the Brahmana rose with the day. He once more performed his ablutions in the sacred waters of the Vahuda and then ignited his homa fire and worshipped it with the aid of many foremost of Vedic mantras.[193] He then worshipped with due rites both Rudra and his spouse Uma, and rested for some more time by the side of that lake in the course of the Vahuda whose shores he had reached. Refreshed by such rest, he set out from that region and then proceeded towards Kailasa. He then beheld a gate of gold that seemed to blaze with beauty. He saw also the Mandakini and the Nalini of the high-souled Kuvera, the Lord of Treasures.[194] Beholding the Rishi arrived there, all the Rakshasas having Manibhadra for their head, who were engaged in protecting that lake abounding with beautiful lotuses, came out in a body for welcoming and honouring the illustrious traveller. The Rishi worshipped in return those Rakshasas of terrible prowess and asked them to report, without delay, his arrival unto the Lord of Treasures. Requested by him to do this, those Rakshasas, O king, said unto him,--'King Vaisravana, without waiting for the news from us, is coming of his own accord to thy presence. The illustrious Lord of Treasures is well acquainted with the object of this thy journey. Behold him,--that blessed Master,--who blazes with his own energy.
