Matsya Purana — Characteristics of Dvāpara and Kali Yugas
वाङ्मनःकर्मभिर्दुःखैर् निर्वेदो जायते ततः निर्वेदाज्जायते तेषां दुःखमोक्षविचारणा //
vāṅmanaḥkarmabhirduḥkhair nirvedo jāyate tataḥ nirvedājjāyate teṣāṃ duḥkhamokṣavicāraṇā //
From the sufferings born of speech, mind, and actions, dispassion (nirveda) arises; and from that dispassion there arises in them the inquiry into liberation from sorrow.
It does not describe cosmic pralaya directly; it presents an inner, psychological sequence—suffering arising from speech, mind, and action leads to dispassion, which then prompts inquiry into liberation.
It frames ethical self-governance: a king or householder should discipline speech (vāk), mind (manas), and actions (karma). Recognizing the suffering produced by unrestrained conduct matures into vairāgya and a deliberate search for freedom from suffering—supporting righteous rule and responsible living.
No direct Vastu or ritual rule appears here; the takeaway is foundational—inner purification and restraint of vāk-manas-karma are treated as prerequisites for higher religious aims, including serious engagement with rites, vows, and sacred works.
