Matsya Purana — Nārāyaṇa as Haṃsa in the Cosmic Ocean: Vedic Yajña-Puruṣa and Mārkaṇḍeya’s Vi...
पुरुषो यज्ञ इत्येतद् यत्परं परिकीर्तितम् यश्चान्यः पुरुषाख्यः स्यात् स एष पुरुषोत्तमः //
puruṣo yajña ityetad yatparaṃ parikīrtitam yaścānyaḥ puruṣākhyaḥ syāt sa eṣa puruṣottamaḥ //
That supreme principle which is proclaimed as “the Person is the Sacrifice (Yajña)”—and that other one who is known by the name ‘Puruṣa’—he indeed is the Puruṣottama, the Supreme Person.
Indirectly, it frames the Supreme Reality as Puruṣottama—the same ultimate principle that remains constant through cosmic cycles, including pralaya; the verse emphasizes identity of the Supreme Person with the cosmic sacrificial order rather than narrating pralaya events.
By identifying the Supreme as Yajña, it underlines that righteous rule and household life should be anchored in yajña—i.e., disciplined offerings, charity, and duty performed as sacred service to the Supreme (Puruṣottama).
Ritually, it gives the key theology behind sacrifice: Yajña is not merely a procedure but is rooted in the Supreme Person; this supports Matsya Purana’s broader ritual worldview where rites (including consecrations and offerings) are oriented to Puruṣottama.
