Vaisampayana continued, “Then all the artisans, the principal counsellors, and the highly wise Vidura said unto Dhritarashtra’s son, “All the preparations for the excellent sacrifice have been made, O king; and the time also hath come, O Bharata. And the exceedingly precious golden plough hath been constructed.’ Hearing this, O monarch, that best of kings, Dhritarashtra’s son commanded that prime among sacrifices to be commenced. Then commenced that sacrifice sanctified by mantras, and abounding in edibles, and the son of Gandhari was duly initiated according to the ordinance. And Dhritarashtra, and the illustrious Vidura, and Bhishma, and Drona, and Kripa, and Karna, and the celebrated Gandhari experienced great delight. And, O foremost of kings, Duryodhana despatched swift messengers to invite the princes and the Brahmanas. And mounting fleet vehicles they went to the (respective) directions assigned to them. Then to a certain messenger on the point of setting out, Dussasana said, ‘Go thou speedily to the woods of Dwaita; and in that forest duly invite the Brahmanas and those wicked persons, the Pandavas.’ Thereupon, he repaired thither, and bowing down to all the Pandavas, said, ‘Having acquired immense wealth by his native prowess, that best of kings and foremost of Kurus, Duryodhana, O monarch, is celebrating a sacrifice. Thither are going from various directions the kings and the Brahmanas. O king, I have been sent by the high-souled Kaurava. That king and lord of men, Dhritarashtra’s son, invites you. It behoveth you, therefore, to witness the delightful sacrifice of that monarch.’
