v2.c30.s11.7

The Atyagniṣṭoma is closely connected with the Ṣoḍaçin, though in the view of the ritual texts it is treated as if it were simply an Agniṣṭoma with an extra Stotra and Çastra. It is really a Ṣoḍaçin in which the three Stotras and Çastras of the Ukthya, and of course the corresponding goblets and Ukthya cup, are omitted. Its real place in the ritual is not as a separate sacrifice at all, but as the form of service on the tenth day of a Daçarātra, a period of ten days, which with an Atirātra before and after it makes up the common form of a Dvādaçāha rite : it must in all probability be treated as a variant form, produced by those theologians who did not approve the addition of the three Stotras and Çastras at the Ukthya rite.
