Matsya Purana — Navagraha Sacrifice for Planetary Pacification and Prosperity
देवपत्न्यो द्रुमा नागा दैत्याश्चाप्सरसां गणाः अस्त्राणि सर्वशस्त्राणि राजानो वाहनानि च //
devapatnyo drumā nāgā daityāścāpsarasāṃ gaṇāḥ astrāṇi sarvaśastrāṇi rājāno vāhanāni ca //
The wives of the gods, the trees, the Nāgas, the Daityas, and the hosts of Apsarases—along with missiles and every kind of weapon, kings, and their vehicles as well—(were all gathered/affected at that time).
It portrays pralaya as a totalizing upheaval in which all classes of beings—divine, terrestrial, and subterranean—as well as royal power and even weaponry/technology are swept into a single overwhelming condition, indicating the leveling force of dissolution.
By explicitly including kings, vehicles, and weapons among what is overtaken, the verse implies the ethical lesson central to the Manu–Matsya dialogue: worldly sovereignty and martial capacity cannot override cosmic law, so a king’s duty is preparedness, dharma, and refuge in righteous guidance rather than pride in force.
No direct Vastu or temple-rule detail appears; however, the comprehensive list (beings, arms, rulers, conveyances) functions as a ritual-cosmological inventory typical of Purāṇic pralaya sections, underscoring that rites and structures too are ultimately subordinate to cosmic cycles.
