Matsya Purana — The Greatness and Procedure of the Aṅgāra
*ईश्वर उवाच तथेति सम्पूज्य स पिप्पलादं वाक्यं चकाराद्भुतवीर्यकर्मा शृणोति यश्चैनमनन्यचेतास् तस्यापि सिद्धिं भगवान्विधत्ते //
*īśvara uvāca tatheti sampūjya sa pippalādaṃ vākyaṃ cakārādbhutavīryakarmā śṛṇoti yaścainamananyacetās tasyāpi siddhiṃ bhagavānvidhatte //
The Lord said: “So be it.” Having duly honoured Pippalāda, he—whose valour and deeds were wondrous—spoke these words. And whoever listens to this with an undivided mind, for him too the Blessed Lord ordains spiritual accomplishment (siddhi).
This verse does not discuss Pralaya directly; it emphasizes the general Purāṇic principle that attentive, single-minded listening to sacred teaching yields divine attainment (siddhi).
It highlights a practical dharma: honoring learned sages (like Pippalāda) and cultivating focused śravaṇa (listening) to dharmic instruction—disciplines recommended for householders and rulers alike to gain right conduct and spiritual merit.
No Vāstu/temple-architecture rule appears here; the ritual note is the act of “sampūjya” (duly honoring/worshipping) a sage before receiving or transmitting instruction.
