Matsya Purana — The Origin of Yajña in Tretā Yuga and the Debate on Animal Sacrifice vs. Non-...
इत्युक्तमात्रो नृपतिः प्रविवेश रसातलम् ऊर्ध्वचारी नृपो भूत्वा रसातलचरो ऽभवत् //
ityuktamātro nṛpatiḥ praviveśa rasātalam ūrdhvacārī nṛpo bhūtvā rasātalacaro 'bhavat //
No sooner had this been spoken than the king entered Rasātala. Though becoming a ruler able to move upward at will, he became one who roamed through Rasātala, the nether regions.
This verse does not describe Pralaya directly; it highlights Puranic cosmology by depicting Rasātala as an accessible realm and presenting extraordinary mobility (ascending/descending) as a narrative motif rather than a dissolution event.
Indirectly, it frames the king as an active seeker and agent who follows instruction immediately (“as soon as it was said”), reflecting the ideal of prompt, disciplined action—an ethical tone often applied to royal conduct in Purāṇic narratives.
No explicit Vāstu or ritual procedure is stated in this verse; its main significance is cosmographical—Rasātala as a named nether realm—useful for contextual indexing of Matsya Purana cosmology rather than temple-building rules.
