Matsya Purana — Characteristics of Dvāpara and Kali Yugas
विप्राणां कर्मदोषैस्तैः प्रजानां जायते भयम् हिंसा मानस्तथेर्ष्या च क्रोधो ऽसूयाक्षमाधृतिः //
viprāṇāṃ karmadoṣaistaiḥ prajānāṃ jāyate bhayam hiṃsā mānastatherṣyā ca krodho 'sūyākṣamādhṛtiḥ //
From those faults in the actions of the Brahmanas (vipra), fear arises among the people—violence, arrogance, jealousy, anger, malice, lack of forgiveness, and loss of steadiness (self-control).
This verse is not about cosmic pralaya; it describes a moral “social dissolution,” where public fear arises when religious leaders fall into violence, pride, jealousy, anger, and unforgiving behavior.
It implies that rulers and householders must ensure ethical leadership and curb these vices in society—because misconduct among respected teachers (vipras) spreads instability and fear among the people, undermining rajadharma (good governance).
No direct Vastu/temple-rule detail appears here; the ritual takeaway is ethical: rites and religious authority become socially harmful when paired with violence, arrogance, jealousy, anger, malice, and lack of forgiveness.
