Matsya Purana — Nārāyaṇa as Haṃsa in the Cosmic Ocean: Vedic Yajña-Puruṣa and Mārkaṇḍeya’s Vi...
व्यक्तमव्यक्तयोगं माम् अवगच्छासुरद्विषम् अहमेकाक्षरो मन्त्रस् त्र्यक्षरश्चैव तारकः //
vyaktamavyaktayogaṃ mām avagacchāsuradviṣam ahamekākṣaro mantras tryakṣaraścaiva tārakaḥ //
Know Me—the foe of the Asuras—as the One who is the union of the manifest and the unmanifest. I am the one-syllable mantra, and I am also the three-syllabled Tāraka (saving) mantra.
It identifies the Supreme as spanning both the manifest world (vyakta) and the unmanifest principle (avyakta), implying that even through cosmic cycles like pralaya, the Lord remains the underlying reality that transcends and supports both states.
By presenting the Lord as the Tāraka mantra and the protector against adharma (asura-dviṣ), it frames rulership and household life as grounded in worship, mantra-discipline, and protection of dharma—inner realization supporting outer ethical governance.
Ritually, it emphasizes mantra-upāsanā: the Lord is invoked as ekākṣara and as the three-syllabled Tāraka mantra, supporting japa and initiation practices that often accompany temple worship and consecration rites described elsewhere in the Matsya Purana.
