Matsya Purana — The Greatness of Prayaga and the Supremacy of Cow-Donation
गीतवाद्यविनिर्घोषैः प्रसुप्तः प्रतिबुध्यते यावन्न स्मरते जन्म तावत्स्वर्गे महीयते //
gītavādyavinirghoṣaiḥ prasuptaḥ pratibudhyate yāvanna smarate janma tāvatsvarge mahīyate //
Awakened from sleep by the resounding music of songs and instruments, he remains honored in heaven so long as he does not remember his former birth on earth.
This verse is not about Pralaya; it describes the post-death experience in Svarga, emphasizing that heavenly honor/enjoyment continues while earthly identity and birth-memory remain unaroused.
It supports the Matsya Purana’s broader karma framework: righteous conduct, charity, and dharmic duties yield puṇya whose results are experienced in Svarga—yet those results are temporary and tied to the mind’s shifting states and eventual return to rebirth.
No Vāstu or temple-architecture rule appears here; the only “ritual-cultural” motif is celestial music (gīta-vādya) as a marker of heavenly enjoyment and honor.
