that tithi and afternoon are assigned for the pitṛs by Brahmā himself¹⁹⁵ Sometimes even a combination not approved by yugmavākya has to be accepted for the performance of a rite e. g when aṣṭamī with Rohiṇī nakṣatra exists (in Kṛṣṇājanmā-vrata) the fast should be observed on that Aṣṭamī, though it may be combined with 7th tithi (and not on 9th as yugmavākya requires).¹⁹⁶ Sometimes, even though a tithi be pūrnā, it is passed over in favour of a viddhā one.¹⁹⁷ Suppose there is Ekādaśī in the bright half from sunrise to sunrise on a certain day and there is Ekādaśī on the next day for two ghaṭikās, then there is Dvādaśī for 59 ghaṭikās in extent; thus trayodaśī commences the day after just one ghaṭikā after sunrise. According to this verse of Pracetas there is to be no upavāsa on the Ekādaśī, though it is pūrnā, but the fast will be observed on Dvādaśī, and the *pāraṇā* in order to be celebrated on dvādaśī will have to be during the first ghaṭikā of the third day from ekādaśī or earlier. But if the Dvādaśī in this case be only for 55 ghaṭikās, trayodaśī will begin three ghaṭikās before sunrise; if *pāraṇā* be done at sunrise it will be on the 13th and not on the 12th. In this latter case, according to Pracetas, the Upavāsa will have to be on the pūrnā Ekādaśī in order that the pāraṇā may be on 12th.
