Matsya Purana — Yayāti and the Kings’ Dialogue on Heavenly Worlds
अलिप्समानस्य तु मे यदुक्तं न तत्तथास्तीह नरेन्द्रसिंह अस्य प्रदानस्य यदेव युक्तं तस्यैव चानन्तफलं भविष्यम् //
alipsamānasya tu me yaduktaṃ na tattathāstīha narendrasiṃha asya pradānasya yadeva yuktaṃ tasyaiva cānantaphalaṃ bhaviṣyam //
But what I said about one who gives without seeking anything in return does not apply here, O lion among kings. For this act of giving, whatever is truly appropriate and rightly fitted—of that alone will the reward be endless.
This verse is not about Pralaya; it teaches Dāna-Dharma—how the spiritual “fruit” of giving depends on propriety and fitness rather than mere claim of selfless intent.
It instructs rulers (and by extension householders) that charity must be guided by dharmic suitability—right context, right recipient, and right manner—so that the merit becomes enduring.
No Vāstu or temple-building detail appears here; the ritual takeaway is that dāna is a regulated dharmic act where “yukta” (properly done) determines the magnitude of the result.
