iii. 50 (xv. 6). The Asuras took refuge in the litany of the Maitrāvaruṇa; Indra said 'Who with me will repel hence these Asuras?' 'I too' replied Varuṇa. Therefore the Maitrāvaruṇa recites (a litany) to Indra and Varuṇa at the third pressing, for Indra and Varuṇa drove them thence. Being driven thence, the Asuras took refuge in the litany of the Brāhmaṇācchaṅsin; Indra said 'Who with me will repel these Asuras hence?' 'I too' replied Bṛhaspati. Therefore the Brāhmaṇācchaṅsin recites to Indra and Bṛhaspati at the third pressing, for Indra and Bṛhaspati drove them thence. Being driven thence, the Asuras took refuge in the litany of the Achāvāka; Indra said 'Who with me will repel them hence?' 'I too' replied Viṣṇu. Therefore the Achāvāka recites to Indra and Viṣṇu at the third pressing, for Indra and Viṣṇu drove them thence. Jointly with Indra the deities are celebrated; a couple is a pairing; therefore from a couple a pairing is produced, for propagation; he is propagated with offspring and cattle who knows thus. There are four offerings to the seasons of the Potṛ and the Neṣṭṛ, and six verses; they make up the tenfold Virāj; thus in the tenfold Virāj they establish the sacrifice.
