v2.c30.s18.6

The beginning of this Sattra ² is variously prescribed, at the full moon of Phālguna or Caitra, or four days before the full moon of these months or of Māgha. The middle day, the Viṣuvant, divides it into two halves, of which the latter is in many respects intended to be the reverse of the former. The scheme of the offering is a Prāyaṇīya Atirātra, a Caturviñça day on which the twenty-four-fold Stoma is used, the form being either an Agniṣṭoma or an Ukthya; five months each of four Abhiplava Ṣaḍahas and one Pṛṣṭhya; a sixth one of one Pṛṣṭhya, three Abhiplavas, one Abhijit, an Agniṣṭoma rite, and three Svarasāman days making up 28, to which the first two days are added to complete the month. Then comes the Viṣuvant. The second half-year has as the seventh month three Svarasāmans, one Viçvajit, one Pṛṣṭhya, and three Abhiplavas; then months 8 to 11 have one Pṛṣṭhya and four Abhiplavas each, and the last has three Abhiplavas, one Āyus day, one Go day, one Daçarātra, and the Mahāvrata and Udayanīya days.
