Matsya Purana — Manvantaras
आत्मार्थे वा परार्थे वा इन्द्रियाणीह यस्य वै विषये न प्रवर्तन्ते दमस्यैतत्तु लक्षणम् //
ātmārthe vā parārthe vā indriyāṇīha yasya vai viṣaye na pravartante damasyaitattu lakṣaṇam //
Whether for one’s own benefit or for another’s, when a person’s senses here do not rush toward sense-objects—this indeed is the defining mark of dama (self-restraint).
Nothing directly about pralaya is stated here; the verse focuses on ethical discipline—defining dama as the senses not moving toward objects, regardless of personal or altruistic motive.
It frames self-mastery as foundational: a king or householder should not let the senses chase pleasures even under the pretext of “for my benefit” or “for others’ benefit,” since stable governance and righteous living depend on restraint.
No vastu/temple or ritual procedure is mentioned; the takeaway is inner qualification—self-control—often treated in the Purana as a prerequisite for successful vows, worship, and righteous action.
