Matsya Purana — The Origin of Yajña in Tretā Yuga and the Debate on Animal Sacrifice vs. Non-...
य इन्द्रियात्मका देवा यज्ञभागभुजस्तु ते तान्यजन्ति तदा देवाः कल्यादिषु भवन्ति ये //
ya indriyātmakā devā yajñabhāgabhujastu te tānyajanti tadā devāḥ kalyādiṣu bhavanti ye //
Those deities who are of the very nature of the senses, and who partake of their allotted share in the yajña—when duly worshipped, those very deities become manifest in the worshipper’s life as auspicious powers and the like.
It does not describe Pralaya directly; it frames a sustaining cosmic principle: deities function through the senses and are maintained through yajña, implying an ordered cosmos upheld by ritual reciprocity rather than dissolution.
It supports the householder/kingly duty of maintaining yajña and worship: honoring the deities who operate through the senses brings kalyāṇa (auspicious welfare), aligning personal discipline and public prosperity with ritual obligation.
Ritually, it emphasizes yajña-bhāga (the deity’s “share” in offerings) and the idea that correct worship activates beneficent divine functions; it does not give specific Vāstu or temple-construction rules in this verse.
