The Religion and Philosophy of the Veda and Upanishads v2.c30.s17.4

v2.c30.s17.4

There are many other forms of the Ahīna rite, with more than one and not more than twelve pressing days, making up at most with the Upasads, &c., not over a month. The number of variations is very large indeed, and the different forms are given names, according to the families or individuals who invented or practised them. Of their make-up the most important rule is that they must end with an Atirātra rite, and in all the days of the Abhiplava and Pṛṣṭhya Ṣaḍahas are usually brought into account: of these further particulars will be given below.
