ekaṃ pavitrameko 'rgha ekaḥ piṇḍo vidhīyate
upatiṣṭhatāmityetad deyaṃ paścāttilodakam //

A Brâhmaṇa on the 11th day after death should feast 11 Brâhmaṇas and Kṣatriyas, &c., should feast an uneven number of Brâhmaṇas. On the day following the completion of the period of defilement, one should perform the Ekoddiṣṭa Śrâddha in which all the ceremonies previously described, barring invocation and homa ceremony of Viśvadeva, should be performed. In this Śrâddha, only one kuśa ring should be put on, and only one offering of water (arghya) and ball of food (piṇḍa) should be made. After reciting “*Upatiṣṭhatâm*,” sesamum and a handful of water should be offered.—8-10.
