Matsya Purana — The Greatness and Procedure of the Aṅgāra
एवमुक्तस्तदा शान्तिम् अगमत् कामरूपधृक् संजातस्तत्क्षणाद्राजन् ग्रहत्वम् अगमत्पुनः //
evamuktastadā śāntim agamat kāmarūpadhṛk saṃjātastatkṣaṇādrājan grahatvam agamatpunaḥ //
Thus addressed, the shape-shifting being at once became calm; and, O King, in that very moment—having manifested—he again assumed the state of a graha (a seizing and afflicting spirit).
This verse does not describe pralaya; it focuses on a localized affliction (graha) and its pacification—showing how disorder can be ritually and verbally calmed rather than cosmic dissolution.
By addressing the afflicting force and restoring śānti, the verse implies a king’s duty to secure public welfare—removing fears, portents, and unseen harms through proper counsel, rites, and disciplined response.
The key ritual idea is śānti (pacification) for graha-pīḍā: the verse supports the Matsya Purana’s broader use of appeasement rites to neutralize harmful influences, though no specific Vāstu/temple rule is stated in this line.
