Matsya Purana — Characteristics of Dvāpara and Kali Yugas
पुष्ये भवन्ति जन्तूनां लोभो मोहश्च सर्वशः संक्षोभो जायते ऽत्यर्थं कलिमासाद्य वै युगम् //
puṣye bhavanti jantūnāṃ lobho mohaśca sarvaśaḥ saṃkṣobho jāyate 'tyarthaṃ kalimāsādya vai yugam //
When the time called Puṣya prevails, greed and delusion arise among living beings on every side; and upon the advent of the age of Kali, intense agitation and turmoil come to be.
This verse is not describing cosmic dissolution (pralaya); it describes yuga-lakṣaṇa—psychological and social deterioration (greed, delusion, agitation) that characterizes the onset of Kali-yuga.
It signals that in Kali-yuga rulers and householders must counter greed and delusion through restraint, truthful conduct, fair judgment, and disciplined charity—otherwise society falls into saṃkṣobha (unrest) and instability.
No direct Vāstu or temple-ritual rule is stated here; the takeaway is contextual—ritual and governance in Kali-yuga require heightened purity, self-control, and ethical safeguards because minds are easily disturbed.
