vii. 27 (xxxv. 1). Viçvantara Sauṣadmana, despising the Çyāparṇas, performed a sacrifice without the Çyāparṇas. Perceiving this the Çyāparṇas went to the sacrifice and sat down within the altar. Seeing them he said ‘There sit those doers of an evil deed, speakers of impure speech, the Çyāparṇas; remove them; let them not sit within my altar’. ‘Be it so’ (they replied). They removed them. They being removed cried aloud ‘Heroes had the Kaçyapas among them in the Asitamṛgas who, at the sacrifice from which Janamejaya Pārikṣita excluded the Kaçyapas, won the Soma drinking from the Bhūtavīras. What hero have we among us who will win this Soma drinking?’ ‘I am the hero for you’, said Rāma Mārgaveya; Rāma Mārgaveya was a learned member of the Çyāparṇas. When they were rising up, he said ‘Can it be that they are removing, O king, from the altar one who knows thus?’ ‘What is that thou knowest, O worthless Brahman’ (he replied).
