Matsya Purana — Purūravas Witnesses the Sports of Apsarases and Gandharvas; Attains the Grace...
*राजोवाच अमोघदर्शनाः सर्वे भवन्तस्त्वमितौजसः वरं वितरताद्यैव प्रसादं मधुसूदनात् //
*rājovāca amoghadarśanāḥ sarve bhavantastvamitaujasaḥ varaṃ vitaratādyaiva prasādaṃ madhusūdanāt //
The King said: “All of you possess unfailing vision and immeasurable might. Therefore grant me, this very day, a boon—namely, the gracious favor of Madhusūdana (Viṣṇu).”
This verse does not describe pralaya directly; it shows a king seeking immediate divine grace (prasāda) from Viṣṇu, a common Purāṇic foundation for receiving higher teachings that may include cosmic cycles elsewhere.
It models the kingly ethic of humility and reliance on dharmic, divine guidance: a ruler should seek Viṣṇu’s favor and wise counsel (from the “infallible-seeing” elders) before pursuing major aims or decisions.
No Vāstu or temple-building rule is stated in this verse; its ritual takeaway is the primacy of seeking Viṣṇu’s prasāda (grace) as the auspicious starting point for rites, vows, or subsequent instructions.
