Matsya Purana — The Origin of Yajña in Tretā Yuga and the Debate on Animal Sacrifice vs. Non-...
प्राचीनबर्हिः पर्जन्यो हविर्धानादयो नृपाः एते चान्ये च बहवस् ते तपोभिर्दिवं गताः //
prācīnabarhiḥ parjanyo havirdhānādayo nṛpāḥ ete cānye ca bahavas te tapobhirdivaṃ gatāḥ //
King Prācīnabarhi, King Parjanya, Havirdhāna and others—these rulers, and many more besides, attained heaven through the power of their austerities (tapas).
This verse does not describe Pralaya; it highlights a genealogical-ethical theme: certain kings reached heaven through tapas (austerity), presenting moral exemplars rather than cosmic dissolution.
It links kingship with spiritual discipline: rulers are portrayed as capable of attaining svarga through tapas, implying that royal power is ideally governed by self-restraint, vows, and dharmic conduct.
No explicit Vastu or temple-architecture rule appears here; the closest ritual implication is that tapas (often paired with vrata and yajña in Purāṇic ethics) is treated as a recognized means to higher worlds.
