Matsya Purana — Yayāti and the Kings’ Dialogue on Heavenly Worlds
*वसुमानुवाच पृच्छाम्यहं वसुमानौषदश्विर् यद्यस्ति लोको दिवि मह्यं नरेन्द्र यद्यन्तरिक्षे प्रथितो महात्मन् क्षेत्रज्ञं त्वां तस्य धर्मस्य मन्ये //
*vasumānuvāca pṛcchāmyahaṃ vasumānauṣadaśvir yadyasti loko divi mahyaṃ narendra yadyantarikṣe prathito mahātman kṣetrajñaṃ tvāṃ tasya dharmasya manye //
Vasumān said: “I, Vasumān, ask you, O king, whether there exists for me a world in heaven, or whether my destiny is renowned in the mid-region (antarikṣa). O great-souled one, I regard you as kṣetrajña, the knower of the field, and therefore as one who knows the dharma that leads to that world.”
This verse does not describe pralaya directly; it reflects Puranic cosmology by distinguishing realms such as heaven (divi) and the mid-region (antarikṣa), implying a moral order where destinations are tied to dharma.
Vasumān approaches the king as a moral authority, implying a Rajadharma ideal: the ruler should be a guide in dharma and in understanding the karmic consequences that lead to higher or intermediate realms.
No Vāstu or temple-architecture rule is stated in this verse; its ritual implication is indirect—right conduct (dharma) is presented as the decisive ‘procedure’ leading to auspicious post-death realms.
