Matsya Purana — The Greatness and Procedure of the Aṅgāra
भक्त्या यस्तु पुनः कुर्याद् एवमङ्गारकाष्टकम् चतुरो वाथ वा तस्य यत्पुण्यं तद्वदामि ते //
bhaktyā yastu punaḥ kuryād evamaṅgārakāṣṭakam caturo vātha vā tasya yatpuṇyaṃ tadvadāmi te //
But whoever, with devotion, recites this Aṅgārakāṣṭaka again—whether four times, or even more—of that person, the spiritual merit earned, I shall now tell you.
This verse does not discuss pralaya; it focuses on devotional recitation (Aṅgārakāṣṭaka) and the resulting merit (puṇya).
It presents a householder-friendly, repeatable devotional practice: reciting a graha-stotra with bhakti to accrue merit—an ethical-spiritual discipline supporting orderly life, self-restraint, and auspicious conduct.
The ritual significance is japa/recitation count: performing the Aṅgārakāṣṭaka repeatedly (four times or more) is prescribed as a merit-generating observance; no Vāstu or temple-construction rule is stated in this verse.
