Matsya Purana — Characteristics of Dvāpara and Kali Yugas
प्रध्वंसश्चैव वर्णानां कर्मणां तु विपर्ययः यात्रा वधः परो दण्डो मानो दर्पो ऽक्षमा बलम् //
pradhvaṃsaścaiva varṇānāṃ karmaṇāṃ tu viparyayaḥ yātrā vadhaḥ paro daṇḍo māno darpo 'kṣamā balam //
There will be the ruin of the social orders (varṇas), and the proper duties (works) will be turned upside down. Expeditions will become slaughter; excessive punishment will prevail; and pride, arrogance, and intolerance will be taken as strength.
This verse is not about cosmic dissolution (Pralaya); it describes social dissolution—dharma collapses as varṇa-duties are ruined and values become inverted.
It warns rulers against “paro daṇḍa” (excessive coercion) and against treating pride and intolerance as power—true rajadharma preserves order through measured justice and restraint.
No direct vastu/ritual rule is stated; the significance is ethical: when dharma is reversed, even rituals and social institutions lose their proper intent and become distorted.
