Matsya Purana — Nārāyaṇa as Haṃsa in the Cosmic Ocean: Vedic Yajña-Puruṣa and Mārkaṇḍeya’s Vi...
तदेष वै वेदमयः पुरुषो यज्ञसंज्ञितः वेदाश्चैतन्मयाः सर्वे साङ्गोपनिषदक्रियाः //
tadeṣa vai vedamayaḥ puruṣo yajñasaṃjñitaḥ vedāścaitanmayāḥ sarve sāṅgopaniṣadakriyāḥ //
Indeed, this Puruṣa is made of the Veda and is known as Yajña (the Sacrifice). And all the Vedas are of his very essence—together with their auxiliaries, the Upaniṣads, and the ritual procedures.
Indirectly, it frames the cosmic order as grounded in Yajña-Puruṣa: even across cycles like pralaya and re-creation, the Vedic principle of sacrifice and sacred knowledge is presented as the enduring foundation of dharma and cosmic continuity.
By identifying the Supreme as Yajña and the Vedas as his essence, the verse supports the Matsya Purana’s ethic that householders and kings uphold society through Vedic duties—especially yajñas, study, and correct observance of prescribed rites—since these acts align human governance and domestic life with cosmic law.
The ritual significance is explicit: Veda, Vedāṅgas, Upaniṣads, and kriyā (procedures) are treated as a unified sacrificial system centered on Yajña-Puruṣa—implying that correct ritual method (kriyā) and its textual supports are essential for valid worship and consecratory acts.
