Matsya Purana — The Rite and Glory of Meru-Dāna: The Tenfold ‘Gift of Meru’ and Mountain-Offe...
अप्सरोगणगन्धर्वैर् आकीर्णेन विराजता विमानेन दिवः पृष्ठम् आयाति स्म निषेवित धर्मक्षये राजराज्यम् आप्नोतीह न संशयः //
apsarogaṇagandharvair ākīrṇena virājatā vimānena divaḥ pṛṣṭham āyāti sma niṣevita dharmakṣaye rājarājyam āpnotīha na saṃśayaḥ //
Adorned with a radiant celestial chariot, crowded with hosts of Apsarases and Gandharvas, he reaches the heights of heaven. And when that merit of dharma is exhausted, he attains sovereign kingship on earth—of this there is no doubt.
This verse is not about pralaya; it teaches karmic results: merit leads to heavenly enjoyment, and after that merit is spent one returns to earthly life with the fruit of royal sovereignty.
It frames dharma as an investable moral force: by practicing righteous conduct (and allied duties such as generosity, protection, and ritual obligations), one gains svarga first and later a high birth and kingship—encouraging rulers/householders to uphold dharma for both spiritual and worldly stability.
No Vāstu or temple-building rule is stated here; the only “technical” imagery is the vimāna as a heavenly vehicle, used to describe the prestige of svarga attained through dharma.
