Matsya Purana — Omens in Tripura and the Nārada–Maya Dialogue on Dharma
उत्पथान्मार्गमागच्छेन् मार्गाच्चेव विमार्गताम् विनाशस्तस्य निर्देश्य इति वेदविदो विदुः //
utpathānmārgamāgacchen mārgācceva vimārgatām vināśastasya nirdeśya iti vedavido viduḥ //
One should come back to the true path from a wrong course; but if one abandons the right path and turns to a perverse way, the learned in the Veda declare that his ruin is certain and inevitable.
This verse is not about cosmic pralaya; it uses “path” language to describe moral order—returning to dharma preserves one’s well-being, while deliberate deviation leads to collapse.
For both king and householder, it frames governance and daily life as “mārga” (dharma-guided conduct): mistakes can be corrected by returning to right practice, but knowingly abandoning dharma for harmful policies or habits is said to end in ruin.
No direct Vastu or ritual rule is stated; indirectly, it supports the Vastu-Shastra principle that correctness (mārga) matters—departures from prescribed measures and rites are treated as causes of failure and loss.
