Matsya Purana — Characteristics of Dvāpara and Kali Yugas
स्वाप्रदानास् तदा ते वै लोभाविष्टास्तु वृन्दशः उपहिंसन्ति चान्योन्यं प्रलुम्पन्ति परस्परम् //
svāpradānās tadā te vai lobhāviṣṭāstu vṛndaśaḥ upahiṃsanti cānyonyaṃ pralumpanti parasparam //
Then, impelled by greed, those groups—clinging to what they claim as their own—injure one another and plunder each other in turn.
It is not a physical Pralaya (cosmic dissolution) verse; it depicts a moral 'dissolution' in Kali-yuga, where greed drives mutual injury and plunder, signaling dharma’s decay.
It warns that unchecked lobha (greed) produces social violence and theft; a king must restrain such banded wrongdoing through danda-nīti (just punishment), while householders must practice self-control, non-injury, and honest livelihood to prevent communal collapse.
No direct Vāstu or ritual procedure is stated; the takeaway is ethical—temples, rites, and civic order lose meaning when society is overtaken by greed and mutual harm.
