Matsya Purana — Manvantaras
ज्ञानं वैराग्यमैश्वर्यं धर्मश्चेति चतुष्टयम् सांसिद्धिकान्यथैतानि अप्रतीतानि तस्य वै //
jñānaṃ vairāgyamaiśvaryaṃ dharmaśceti catuṣṭayam sāṃsiddhikānyathaitāni apratītāni tasya vai //
Knowledge (jñāna), dispassion (vairāgya), lordly power (aiśvarya), and righteousness (dharma)—this set of four is said to be the marks of spiritual accomplishment; and when these are absent, it is indeed a sign that perfection has not been realized.
This verse is not about Pralaya; it defines inner criteria for spiritual accomplishment—knowledge, detachment, spiritual sovereignty, and dharma—rather than cosmic dissolution events.
It frames dharma and disciplined detachment as essential even amid power (aiśvarya). For a king or householder, authority and prosperity are validated when guided by knowledge and righteousness, not mere enjoyment.
No direct Vāstu or ritual rule is stated; the takeaway is foundational: temple-building, gifting, and rites bear higher fruit when grounded in jñāna, vairāgya, and dharma rather than display of wealth.
