Matsya Purana — Rites for Consecrating and Celebrating Trees
ये च लोकाः स्मृतास्तेषां तानिदानीं वदस्व नः यत्फलं लभते प्रेत्य तत्सर्वं वक्तुमर्हसि //
ye ca lokāḥ smṛtāsteṣāṃ tānidānīṃ vadasva naḥ yatphalaṃ labhate pretya tatsarvaṃ vaktumarhasi //
“And concerning the worlds spoken of in tradition—tell us of them now. Also explain in full what reward a person obtains after death; you ought to declare all of that.”
This verse does not describe Pralaya directly; it frames an inquiry into cosmological realms (lokas) and the outcomes experienced after death, which often form part of broader Puranic cosmology discussions.
By asking about post-death results (pretya-phala), the verse underscores a key Matsya Purana theme: dharma should be practiced with awareness of ethical consequences, guiding kings and householders toward righteous conduct for auspicious afterlife outcomes.
No specific Vastu or temple-building rule is stated in this verse; it functions as a transition into teaching about lokas and post-death rewards, which later can connect to ritual merit (puṇya) gained through rites and donations.
