Pahlavi Texts, Part III (SBE24), E.W. West, tr. , at sacred-texts.com
1. The sixty-sixth subject is this, that it is incumbent on all women 2 to order the days (ayyâm) of the Dvâzdah-hômâst 3, because the whole of any sin that may have arisen during menstruation, and at other times, becomes cleared away thereby.
2. And in the commentary of the Vendîdâd it says that every one becomes sanctified in the days of the Dvâzdah-hômâst, and all sins become cleared away from her, like that which occurs at harvest time, when a great wind comes on and carries it off; dust like this the sin departs from her, and the person becomes clean and pure.
3. And, for women 4, there is no duty more indispensable than this; for it is declared in revelation that, when they celebrate a Dvâzdah-hômâst, it is a good work of a hundred thousand Tanâvars 5, and if
it be the days of the Dvâzdah-hômâst it is a good work of a thousand thousand Tanâvars, and when they celebrate it by day it is a good work just like this.
330:2 B29 has 'on the wives of every one,' and J15 has 'on every one.'
330:3 In the Gugarâti version (p. 310) of the long-metre Sad Dar Dastûr Jâmâspji states, in a foot-note, that the Dvâzdah-hômâst consists of a Yazisn ceremony every day for 144 days, in honour of twelve angels, so that each angel is reverenced for twelve successive days. He stated formerly (see Byt. II, 59 n) that this celebration was a Hômâst, and that a Dvâzdah-hômâst was a similar celebration for 264 days in honour of twenty-two angels for twelve days each. It appears, however, from Chap. XLI, 7, 20, that the number of ceremonies may vary with the wealth of the individual.
330:4 Lp omits these thirteen words.
