Shanti Parva 29.66

Upon that highly effulgent golden stake decked with a ring, six thousand gods and Gandharvas danced in joy, and Vishvavasu himself, in their midst played on his Vina the notes according to the rules of concordance. Such the nature of Vishvavasu's music that every creature, wherever he might be, thought that the great Gandharva was playing to him alone.
