Matsya Purana — Catalogue of the Eighteen Puranas
*मुनय ऊचुः पुराणसंख्यामाचक्ष्व सूत विस्तरशः क्रमात् दानधर्ममशेषं तु यथावदनुपूर्वशः //
*munaya ūcuḥ purāṇasaṃkhyāmācakṣva sūta vistaraśaḥ kramāt dānadharmamaśeṣaṃ tu yathāvadanupūrvaśaḥ //
The sages said: “O Sūta, tell us—step by step and in full detail—the number (and classification) of the Purāṇas; and likewise explain completely the dharma of giving (dāna), properly and in the correct sequence.”
This verse does not describe Pralaya directly; it sets up a teaching request, asking Sūta to enumerate the Purāṇas and to explain dāna-dharma in a systematic order.
By requesting “dāna-dharma” in full and in sequence, the sages highlight that charitable giving is a structured duty (not random generosity), relevant to householders and rulers who must practice regulated giving aligned with dharma.
No Vāstu or temple rule is stated in this verse; however, the emphasis on “yathāvat anupūrvaśaḥ” (proper procedure in correct sequence) reflects the Purāṇic method used later for ritual and technical instructions, including architecture and iconography.
