Matsya Purana — Division of Bhārata-varṣa
पृष्टस्त्वेवं तदा विप्रैर् यथाप्रश्नं विशेषतः उवाच ऋषिभिर्दृष्टं पुराणाभिमतं तथा //
pṛṣṭastvevaṃ tadā viprair yathāpraśnaṃ viśeṣataḥ uvāca ṛṣibhirdṛṣṭaṃ purāṇābhimataṃ tathā //
Thus, when questioned in this way by the Brahmin sages, he replied—addressing each query in its particularity—expounding what had been perceived by the seers and what is approved in the Purāṇic tradition.
This verse does not describe pralaya directly; it establishes the teaching method—answers are given precisely as asked and grounded in rishi-seen Purāṇic authority, which frames later cosmology and pralaya teachings as reliable.
It signals that dharma instructions in the Matsya Purana are delivered case-by-case (“according to the question”), implying that royal and household duties are to be understood contextually and in line with established Purāṇic norms.
No specific vastu or ritual rule is stated here; rather, it introduces that forthcoming ritual and temple-architecture guidance is presented as rishi-validated, Purāṇa-approved instruction responding to detailed inquiries.
