Matsya Purana — Characteristics of Dvāpara and Kali Yugas
नष्टे श्रौतस्मृते धर्मे कामक्रोधवशानुगाः निर्मर्यादा निरानन्दा निःस्नेहा निरपत्रपाः //
naṣṭe śrautasmṛte dharme kāmakrodhavaśānugāḥ nirmaryādā nirānandā niḥsnehā nirapatrapāḥ //
When dharma founded on Śruti and Smṛti is lost, people become driven by lust and anger—without restraint, without joy, without affection, and without shame.
It does not describe cosmic pralaya directly; it depicts a moral “dissolution” where scriptural dharma collapses and society becomes ruled by kāma and krodha.
It implies that rulers and householders must preserve Śruti–Smṛti based conduct—cultivating restraint, shame (moral conscience), and social boundaries—otherwise lawlessness and cruelty spread.
No Vāstu or iconographic rule is stated; the ritual takeaway is that when Śrauta–Smārta norms are abandoned, sacred rites lose authority and communities drift into adharmic practice.
