Matsya Purana — The Rite of the Vibhūti-Dvādaśī Vow
यावद्युगसहस्राणां शतमष्टोत्तरं भवेत् तावत्स्वर्गे वसेद्ब्रह्मन् भूपतिश्च पुनर्भवेत् //
yāvadyugasahasrāṇāṃ śatamaṣṭottaraṃ bhavet tāvatsvarge vasedbrahman bhūpatiśca punarbhavet //
O Brahman, for as long as one hundred and eight thousand yugas endure, so long does he dwell in heaven—and then he is born again as a king upon the earth.
This verse does not discuss Pralaya; it teaches karmic “fruit” (phala)—a long stay in Svarga followed by rebirth—within the moral economy of merit.
It frames dharmic action (often charity, ritual support, and righteous conduct in Rajadharma contexts) as yielding Svarga and an auspicious rebirth as a ruler—encouraging householders and kings to uphold dharma and patronage.
No Vāstu or temple-building rule is stated here; the verse is a phala-śruti style claim about heavenly reward and subsequent royal rebirth.
