tatra āṣāḍhaśuklāt kulapūrṇimādināntaṃ kāryaṃ pavitrakam tatra kārttikakṛṣṇapañcadaśī kulacakraṃ nityācakraṃ pūrayati iti śrīnityātantravidaḥ
In this matter, the pavitraka is to be performed from the bright fortnight of Āṣāḍha up to the day of the Kula full moon; therein the new moon of the dark fortnight of Kārttika fulfills the Kula circle and the circle of the Nityā goddesses — so say the knowers of the venerable Nityātantra.
