Matsya Purana — Devayānī–Śarmiṣṭhā Dialogue: Yayāti’s Transgression
ऋतुकामां स्त्रियं यस्तु गम्यां रहसि याचितः नोपैति यो हि धर्मेण ब्रह्महेत्युच्यते बुधैः //
ṛtukāmāṃ striyaṃ yastu gamyāṃ rahasi yācitaḥ nopaiti yo hi dharmeṇa brahmahetyucyate budhaiḥ //
Si une femme en sa saison féconde, légitimement accessible selon le dharma, invite en secret un homme et que celui-ci ne vient pas à elle conformément au dharma, les sages déclarent qu’il porte une faute comparable à celle d’un « meurtrier de brahmane » (brahma-hatyā).
This verse does not discuss pralaya; it focuses on dharma in household life, classifying refusal of a lawful conjugal request during the fertile period as a grave moral fault.
It is primarily a gṛhastha (householder) rule: a husband (or lawful partner) is expected to respond righteously to a permissible private invitation during ṛtu-kāla, treating procreation and marital duty as part of dharma; for a king, it reinforces governance rooted in strict ethical discipline and control of personal conduct.
No vastu/temple-architecture rule is stated here; the only ritual-ethical implication is the emphasis on ṛtu-kāla (fertile season) as a dharmic framework for household life and progeny.
