Mbh 12.39.1b

Entering the apartments, blessed Yudhishthira approached the household gods and worshipped them with gems and scents and floral wreaths. Possessed of great fame and prosperity, the king came out once more and beheld a number of Brahmanas waiting with auspicious articles in their hands (for pronouncing benedictions on him). Surrounded by those Brahmanas desirous of uttering benedictions on him, the king looked beautiful like the spotless moon in the midst of the stars. Accompanied by his priest Dhaumya and his eldest uncle, the son of Kunti cheerfully worshipped, with due rites, those Brahmanas with (gifts of) sweets, gems, and gold in profusion, and kine and robes, O monarch, and with diverse other articles that each desired. Then loud shouts of "This is a blessed day" arose, filling the entire welkin, O Bharata. Sweet to the ear, that sacred sound was highly gratifying to the friends and well-wishers (of the Pandavas). The king heard that sound uttered by those learned Brahmanas and that was as loud and clear as the sound of a flock of swans. He listened also to the speeches, fraught with melodious words and grave import, of those persons well conversant with the Vedas. Then, O king, the peal of drums and the delightful blare of conchs, indicative of triumph, arose. A little while after when the Brahmanas had become silent, a Rakshasa of the name of Charvaka, who had disguised himself as a Brahmana, addressed the king. He was a friend of Duryodhana and stood there in the garb of a religious mendicant. With a rosary, with a tuft of hair on his head, and with the triple staff in his hand, he stood proudly and fearlessly in the midst of all those Brahmanas that had come there for pronouncing benedictions (upon the king), numbering by thousands, O king, and all of whom were devoted to penances and vows. That wicked wight, desirous of evil unto the high-souled Pandavas and without having consulted those Brahmanas, said these words unto the king.'
