यद्यस्ति यत्किंचिदिहास्ति देयं दद्याद्द्विजायात्महिताय सर्वम् मनोरथान्नः सफलीकुरुष्व हिरण्यगर्भाच्युतरुद्ररूपिन् //
yadyasti yatkiṃcidihāsti deyaṃ dadyāddvijāyātmahitāya sarvam manorathānnaḥ saphalīkuruṣva hiraṇyagarbhācyutarudrarūpin //
Whatever is available here and fit to be given—let all of it be given to a dvija (Brāhmaṇa) for one’s own spiritual welfare. O Lord who manifests as Hiraṇyagarbha, as Acyuta, and as Rudra, make our wishes bear fruit.
It does not describe Pralaya directly; instead it presents a theological synthesis—one Supreme Lord appearing as Hiraṇyagarbha (creation), Acyuta (preservation), and Rudra (dissolution)—implying control over all cosmic phases.
It frames dāna as a core dharmic duty: whatever is legitimately available and suitable for gifting should be offered, particularly to a dvija/brāhmaṇa, with the stated aim of ātma-hita (one’s spiritual welfare).
The verse is primarily ritual-ethical rather than architectural; its ritual takeaway is the primacy of charitable offering (dāna) as part of devotional practice and merit-making.
