Matsya Purana — Saptamī Sacred Bath and the Mṛtavatsābhiṣeka Rite for Pacifying Misfortune an...
विप्रेण वेदविदुषा विधिवद्दर्भपाणिना स्थापयित्वा तु चतुरः कुम्भान्कोणेषु शोभनान् //
vipreṇa vedaviduṣā vidhivaddarbhapāṇinā sthāpayitvā tu caturaḥ kumbhānkoṇeṣu śobhanān //
Then, a Brahmin learned in the Vedas—holding sacred darbha grass in his hand and acting according to proper rite—should duly set up four auspicious ritual pots (kumbhas) at the corners.
This verse is not about Pralaya; it prescribes a ritual action—placing four kumbhas at the corners—typical of consecration and protective rite patterns in Vastu/temple procedures.
It implies that major rites (for temples, images, or sacred spaces) should be performed under the guidance of a Veda-trained Brahmin following correct vidhi; a patron-king or householder supports and commissions the rite, ensuring orthopraxy and auspicious arrangement.
It describes kumbha-sthāpana: installing four auspicious ritual pots at the four corners, a standard consecration safeguard that ritually secures the space and aligns the rite with Vastu-oriented corner protection.
