Matsya Purana — Śrāddha Procedure: Types
एवमावाह्य तत्सर्वं वेदमन्त्रैर्यथोदितैः एकाग्नेरेक एव स्यान् निर्वापो दर्विका तथा //
evamāvāhya tatsarvaṃ vedamantrairyathoditaiḥ ekāgnereka eva syān nirvāpo darvikā tathā //
Thus, having invoked all of that as prescribed with Vedic mantras, one should maintain a single sacred fire; and there should be only one act of offering (nirvāpa), performed using the ladle (darvikā) as well.
This verse is not about Pralaya; it gives technical ritual guidance—invocation with Vedic mantras and maintaining a single consecrated fire with a regulated method of oblation.
It aligns with dharma-based discipline in rites: a householder (or a ruler sponsoring rites) should follow prescribed mantras and maintain orderly procedure—one properly established fire and correctly performed offerings—rather than improvised or excessive ritual variations.
Ritually, it stresses ekāgni (one sacred fire) and a standardized nirvāpa using the darvikā ladle—key procedural points for homa/yajña performance, often tied to correct altar/fire arrangement in orthodox practice.
