Matsya Purana — Nārāyaṇa as Haṃsa in the Cosmic Ocean: Vedic Yajña-Puruṣa and Mārkaṇḍeya’s Vi...
आदित्यवर्णः पुरुषो मखे ब्रह्ममयो मखः अहमग्निर्हव्यवाहो यादसां पतिरव्ययः //
ādityavarṇaḥ puruṣo makhe brahmamayo makhaḥ ahamagnirhavyavāho yādasāṃ patiravyayaḥ //
In the sacrifice, the Puruṣa is radiant like the Sun; the sacrifice itself is pervaded by Brahman. I am Agni, the bearer of oblations, and I am the imperishable lord of the waters.
It presents the deity as the imperishable principle present in fire and waters—elements central to Pralaya imagery—implying divine continuity even when worlds dissolve.
By identifying the Lord with yajña and Agni, it reinforces that kings and householders uphold dharma through properly performed sacrifices and offerings, seeing ritual as participation in cosmic order.
Ritually, it centers Agni as the havya-vāha (conduit of offerings) and frames yajña as brahma-maya, a key premise behind consecration rites (pratiṣṭhā) that also underpin Puranic temple-ritual procedure.
