Matsya Purana — The Origin of Yajña in Tretā Yuga and the Debate on Animal Sacrifice vs. Non-...
आलब्धेषु च मध्ये तु तथा पशुगणेषु वै आहूतेषु च देवेषु यज्ञभुक्षु ततस्तदा //
ālabdheṣu ca madhye tu tathā paśugaṇeṣu vai āhūteṣu ca deveṣu yajñabhukṣu tatastadā //
And at that time—when the offerings had been duly taken up, when the animals intended for the rite had been arranged in proper order, and when the gods, the enjoyers of the sacrifice, had been invoked—then the ritual proceeded further according to rule.
This verse is not about Pralaya; it focuses on yajña-krama (ritual sequence), emphasizing correct preparation, ordering, and invocation before proceeding.
It underscores dharmic discipline in performing rites: a householder (and a king sponsoring public sacrifices) should ensure materials are properly prepared, the ritual order is maintained, and the devas are formally invoked before the next steps of the sacrifice.
Ritually, it highlights sequencing—preparation of offerings, arrangement of sacrificial animals, and invocation of the yajña-partaking deities—showing that efficacy depends on correct procedural order (krama) rather than mere performance.
