Matsya Purana — Tripura’s Prosperity
अथ दैवपरिध्वस्ता दानवास्त्रिपुरालयाः हित्वा सत्यं च धर्मं च अकार्याण्युपचक्रमुः //
atha daivaparidhvastā dānavāstripurālayāḥ hitvā satyaṃ ca dharmaṃ ca akāryāṇyupacakramuḥ //
Then the Dānavas who dwelt in Tripura—shattered by the decree of the gods—abandoned truth and righteousness, and began to engage in forbidden deeds.
It does not describe cosmic Pralaya; it depicts a moral and political “dissolution” where divine pressure leads the Tripura-dwelling Danavas to collapse into adharma by abandoning satya and dharma.
It highlights the core duty to uphold satya (truthfulness) and dharma (right conduct). When these are forsaken, one naturally turns to akārya (prohibited acts), a warning relevant to kings (governance by dharma) and householders (ethical restraint).
The key term is “Tripura-ālayāḥ” (dwellers in Tripura), pointing to the famed three-cities motif; this verse itself gives no Vāstu or ritual rule, but sets narrative context for the Tripura tradition often linked with temple/ritual storytelling.
