History of Dharmashastra (Ancient and Mediaeval Religious and Civil Law in India) v3.c48.8

v3.c48.8

One who has performed agnyādheya should begin the performance of darśapūrṇamāsa on the first Full Moon day after it. The iṣṭi on the Full-moon day may occupy two days, but all the actions to be performed in it can be compressed into one day.²²⁷⁵ If extended over two days it is performed on the full moon day and the *pratipad* (the first day of the dark half that follows the Full Moon day), the former being called *upavasatha* day²²⁷⁶ and the latter *yajanīya* day. On the upavasatha day agnyanvādhāna (offering fuel-sticks into fire) and paristaraṇa are performed in the case of the pūrṇamāsa rite and on the yajanīya day the rest is performed. If it is the first pūrṇamāsa iṣṭi or the first darśa iṣṭi, then the sacrificer has to perform the Anvārambhaṇīyā iṣṭi, which is briefly described in the note below.²²⁷⁷
