Mbh 3.157.2a

“Then Kunti’s son, Yudhishthira of unfailing prowess, together with his brothers, began to proceed on foot along the mountain path, inhabited by various kinds of beasts. And having dwelt at the mountain slopes, densely overgrown with trees, Pandu’s son on the fourth day reached the Sweta mountain, like unto a mighty mass of clouds, abounding in streams and consisting of a mass of gold and gems. And taking the way directed by Vrishaparva, they reached one by one the intended places, beholding various mountains. And over and over they passed with ease many inaccessible rocks and exceedingly impassable caves of the mountain. And Dhaumya and Krishna and the Parthas and the mighty sage Lomasa went on in a body and none grew tired. And those highly fortunate ones arrived at the sacred and mighty mountain resounding with the cries of birds and beasts and covered with various trees and creepers and inhabited by monkeys, and romantic and furnished with many lotus-lakes and having marshes and extensive forests. And then with their down standing erect, they saw the mountain Gandhamadana, the abode of Kimpurushas, frequented by Siddhas and Charanas and ranged by Vidyadharis and Kinnaris and inhabited by herds of elephants and thronged with lions and tigers and resounding with the roars of Sarabhas and attended by various beasts. And the war-like sons of Pandu gradually entered into the forest of the Gandhamadana, like unto the Nandana gardens, delightful to the mind and heart and worthy of being inhabited and having beautiful groves. And as those heroes entered with Draupadi and the high-souled Brahmanas, they heard notes uttered by the mouths of birds, exceedingly sweet and graceful to the ear and causing delight and dulcet and broken by reason of excess of animal spirits.
