Matsya Purana — The Rohiṇī–Candraśayana Vow
नारी वा रोहिणी चन्द्रशयनं या समाचरेत् सापि तत्फलमाप्नोति पुनरावृत्तिदुर्लभम् //
nārī vā rohiṇī candraśayanaṃ yā samācaret sāpi tatphalamāpnoti punarāvṛttidurlabham //
Whether a woman—or one practising under Rohiṇī (the lunar asterism)—performs the Candraśayana observance, she too attains its fruit: a state from which return to rebirth is hard to come by.
This verse does not discuss Pralaya directly; it emphasizes the soteriological fruit of a vow—attaining a state where return to repeated rebirth becomes difficult.
It frames vrata-practice as accessible beyond gender distinctions and as a legitimate dharmic discipline for householders, promising elevated spiritual results through proper observance.
The ritual significance is the Candraśayana-vrata itself, with an added timing/association marker (Rohiṇī nakṣatra), highlighting that correct observance and auspicious calendrical alignment enhance the vow’s fruit.
