Matsya Purana — Rite and Layout for Consecrating Ponds
कृत्वा तु यज्ञपात्राणि यज्ञोपकरणानि च ऋत्विग्भ्यस्तु समं दत्त्वा मण्डपं विभजेत्पुनः हेमपात्रीं च शय्यां च स्थापकाय निवेदयेत् //
kṛtvā tu yajñapātrāṇi yajñopakaraṇāni ca ṛtvigbhyastu samaṃ dattvā maṇḍapaṃ vibhajetpunaḥ hemapātrīṃ ca śayyāṃ ca sthāpakāya nivedayet //
Having prepared the sacrificial vessels and the other requisites of the sacrifice, one should distribute them equally to the officiating priests; thereafter, one should again apportion the ritual pavilion (maṇḍapa). A golden vessel and a bed should be presented to the installer/architect (sthāpaka).
This verse does not discuss Pralaya; it focuses on ritual protocol—preparing yajña materials, distributing them to priests, and honoring the sthāpaka with specific gifts.
It frames dharmic responsibility in public/household rites: one must properly equip the sacrifice, compensate priests fairly (equal distribution), and honor skilled specialists like the sthāpaka—an ethical guideline for patrons and rulers funding rituals or construction.
It links Vastu/installation work with yajña procedure: the maṇḍapa is to be formally apportioned, and the sthāpaka (architect/installer) receives a defined honorarium (a golden vessel and a bed), indicating the recognized ritual-architectural role in consecration.
