Matsya Purana — Śrāddha Procedure: Types
तृप्ताञ्ज्ञात्वा ततः कुर्याद् विकिरन्सार्ववर्णिकम् सोदकं चान्नमुद्धृत्य सलिलं प्रक्षिपेद्भुवि //
tṛptāñjñātvā tataḥ kuryād vikiransārvavarṇikam sodakaṃ cānnamuddhṛtya salilaṃ prakṣipedbhuvi //
Having ascertained that they are satisfied, one should then perform the scattering-offering (vikiraṇa) meant for all social classes (varṇa); and, lifting up the food together with water, one should pour the water onto the ground.
This verse is not about pralaya; it focuses on dharma in ritual conduct—what one should do after confirming that recipients/guests are satisfied, including a universal scattering-offering and pouring water to the earth.
It frames a householder’s (and by extension a king’s) duty of proper hospitality and orderly ritual completion: verify the guests’ satisfaction, then perform the prescribed distribution/scattering meant for all classes, and conclude with the appropriate handling of food and water offerings.
The significance is ritual, not architectural: it prescribes a vikiraṇa (scattering/distribution) offering for all varṇas and a concluding act of pouring water onto the ground—typical of purification/closure steps in offering rites.
