In that sacrifice of the high-souled son of Kunti, three hundred animals were tied to the stakes setup, including that foremost of steeds. That sacrifice looked exceedingly beautiful as if adorned with the celestial Rishis, with the Gandharvas singing in chorus and the diverse tribes of Apsaras dancing in merriment. It teemed, besides, with Kimpurushas and was adorned with Kinnaras. All around it were abodes of Brahmanas crowned with ascetic success. There were daily seen the disciples of Vyasa, those foremost of regenerate ones, who are compilers of all branches of learning, and well conversant with sacrificial rites. There was Narada, and there was Tumvuru of great splendour. There were Viswavasu and Chitrasena and others, all of whom were proficient in music. At intervals of the sacrificial rites, those Gandharvas, skilled in music and well versed in dancing, used to gladden the Brahmanas who were engaged in the sacrifice.'"
