Matsya Purana — Yadu Lineage
ततो देवा न्यवर्तन्त विज्वरा मुदिताश्च ते न्यस्तशस्त्रेषु दैत्येषु विनिवृत्तास्तदा सुराः //
tato devā nyavartanta vijvarā muditāśca te nyastaśastreṣu daityeṣu vinivṛttāstadā surāḥ //
Then the gods turned back—free from distress and filled with joy. When the demons had laid down their weapons, the deities withdrew from the battle at that time.
This verse does not discuss Pralaya; it depicts a war episode where the devas withdraw once the daityas are disarmed, highlighting restoration of order rather than cosmic dissolution.
It implies a dharmic principle of restraint: once the opponent is disarmed, force should cease—an ethic relevant to kings (just warfare, non-cruelty) and householders (self-control and avoiding needless harm).
No Vāstu or ritual procedure is stated in this verse; its significance is ethical and narrative—cessation of violence when the threat has ended.
