Mbh 3.158.2a

Arshtishena said, ‘During the Parvas sages subsisting on air and water come unto this best of the mountains ranging through the air. And on the summits of the mountain are seen amorous Kimpurushas with their paramours, mutually attached unto each other; as also, O Partha, many Gandharvas and Apsaras clad in white silk vestments; and lovely-looking Vidyadharas, wearing garlands; and mighty Nagas, and Suparnas, and Uragas, and others. And on the summits of the mountain are heard, during the Parvas, sounds of kettle-drums, and tabors, shells and mridangas. O foremost of the Bharatas, even by staying here, ye shall hear those sounds; do ye by no means feel inclined to repair thither. Further, O best of the Bharata race, it is impossible, to proceed beyond this. That place is the sporting-region of the celestials. There is no access thither for mortals. O Bharata, at this place all creatures bear ill-will to, and the Rakshasas chastise, that man who committeth aggression, be it ever so little. Beyond the summit of this Kailasa cliff, is seen the path of the celestial sages. If any one through impudence goeth beyond this, the Rakshasas slay him with iron darts and other weapons. There, O child, during the Parvas, he that goeth about on the shoulders of men, even Vaisravana is seen in pomp and grandeur surrounded by the Apsaras. And when that lord of all the Rakshasas is seated on the summit, all creatures behold him like unto the sun arisen, O best of Bharatas, that summit is the sporting-garden of the celestials, and the Danavas, and the Siddhas, and Vaisravana. And during the Parvas, as Tumburu entertaineth the Lord of treasures, the sweet notes of his song are heard all over the Gandhamadana. O child, O Yudhishthira, here during the Parvas, all creatures see and hear marvels like this. O Pandavas, till ye meet with Arjuna, do ye stay here, partaking of luscious fruits, and the food of the Munis. O child as thou hast come hither, do thou not betray any impertinence.
