Mbh 3.141.1

“Lomasa said, O sons of Pandu, ye have seen many a mountain, and river and town and forest and beautiful tirtha; and have touched with your hands the sacred waters. Now this way leads to the celestial mountain Mandara; therefore be ye attentive and composed. Ye will now repair to the residence of the celestials and the divine sages of meritorious deeds. Here, O king, flows the mighty and beautiful river (Alakananda) of holy water adored by hosts of celestials and sages, and tracing its source to (the site of) the jujube tree. It is frequented and worshipped by high-souled Vaihayasas, Valakhilyas and Gandharvas of mighty souls. Accustomed to sing the Sama hymns, the sages, Marichi, Pulaha, Bhrigu and Angiras, chanted them at this spot. Here the lord of celestials performeth with the Maruts his daily prayers. And the Sadhyas and the Aswins attend on him. The sun, the moon and all the luminaries with the planets resort to this river, alternately by day and by night. O highly fortunate monarch, that protector of the world; Mahadeva, having a bull for his mark, received on his head the fall of the waters of this river, at the source of the Ganga. O children, approach this goddess of the six attributes and bow down before her with concentrated minds.’
