Matsya Purana — Śukra Warns Vṛṣaparvan: The Ripening of Adharma and Devayānī’s Demand for Śar...
अपापशीलं धर्मज्ञं शुश्रूषुं मद्गृहे रतम् वधादनर्हतस्तस्य वधाच्च दुहितुर्मम //
apāpaśīlaṃ dharmajñaṃ śuśrūṣuṃ madgṛhe ratam vadhādanarhatastasya vadhācca duhiturmama //
He is of blameless conduct, a knower of dharma, devoted to service, and attached to my household. He does not deserve to be slain; and by slaying him, my daughter too would be (as good as) slain.
This verse does not address pralaya or cosmology; it focuses on dharma—specifically the injustice and moral consequence of killing an innocent, dharma-knowing person.
It frames a core Rajadharma principle: punishment must be proportionate and never directed at the undeserving. For householders, it emphasizes protecting those who serve faithfully and live righteously under one’s care.
No Vāstu, temple-building, or ritual procedure is mentioned; the verse is ethical-legal in tone, stressing non-violence and just discernment rather than architectural rules.
