Mbh 9.37.1a

Vaishampayana said, "Then Valadeva, O king, proceeded to Vinasana where the Sarasvati hath become invisible in consequence of her contempt for Sudras and Abhiras. And since the Sarasvati, in consequence of such contempt, is lost at that spot, the Rishis, for that reason, O chief of the Bharatas, always name the place as Vinasana. Having bathed in that tirtha of the Sarasvati, the mighty Baladeva then proceeded to Subhumika, situated on the excellent bank of the same river. There many fair-complexioned Apsaras, of beautiful faces, are always engaged in sports of a pure character without any intermission. The gods and the Gandharvas, every month, O ruler of men, repair to that sacred tirtha which is the resort of Brahman himself. The Gandharvas and diverse tribes of Apsaras are to be seen there, O king, assembled together and passing the time as happily as they like. There the gods and the Pitris sport in joy, with sacred and auspicious flowers repeatedly rained over them, and all the creepers also were adorned with flowery loads. And because, O king, that spot is the beautiful sporting ground of those Apsaras, therefore is that tirtha on the excellent bank of the Sarasvati called Subhumika. Baladeva of Madhu's race, having bathed in that tirtha and given away much wealth unto the Brahmanas, heard the sound of those celestial songs and musical instruments. He also saw there many shadows of gods, Gandharvas, and Rakshasas. The son of Rohini then proceeded to the tirtha of the Gandharvas. There many Gandharvas headed by Viswavasu and possessed of ascetic merit, pass their time in dance and song of the most charming kind. Giving away diverse kinds of wealth unto the Brahmanas, as also goats and sheep and kine and mules and camels and gold and silver, and feeding many Brahmanas and gratifying them with many costly gifts that were desired by them, Baladeva of Madhu's race proceeded thence, accompanied by many Brahmanas and eulogised by them.
