Matsya Purana — The Origin of Yajña in Tretā Yuga and the Debate on Animal Sacrifice vs. Non-...
द्रव्यमन्त्रात्मको यज्ञस् तपश्च समतात्मकम् यज्ञैश्च देवानाप्नोति वैराजं तपसा पुनः //
dravyamantrātmako yajñas tapaśca samatātmakam yajñaiśca devānāpnoti vairājaṃ tapasā punaḥ //
Yajña is constituted of offerings (dravya) and mantras, while tapas is constituted of equanimity (samatā). By yajñas one attains the gods; but by tapas one again attains the Vairāja state—the cosmic station akin to Brahmā.
It does not describe Pralaya directly; it outlines a hierarchy of spiritual attainments—yajña leads to deva-realms, while tapas (equanimity) leads to the higher cosmic status called Vairāja, implying ascent through cosmological levels rather than dissolution.
It frames the householder/kingly path as yajña-based (offerings and mantra, supporting gods and social order), while also affirming that inner discipline—samatā (even-mindedness)—is the essence of tapas and yields a higher spiritual fruit.
Ritually, it defines yajña as dravya+mantra (proper substances and correct recitation), a key Matsya Purana ritual principle; there is no direct Vastu or temple-architecture rule in this specific verse.
