Mahāviṣṇu-Mantras: Aṣṭākṣarī, Sudarśana-Astra, Nyāsa Systems, Āvaraṇa-Pūjā, and Prayogas
एषोक्ता विष्णुगायत्री सर्वपापप्रणाशिनी । तारो हृद्भगवान् ङेंतो वासुदेवाय कीर्तितः ॥ ७२ ॥
eṣoktā viṣṇugāyatrī sarvapāpapraṇāśinī | tāro hṛdbhagavān ṅeṃto vāsudevāya kīrtitaḥ || 72 ||
Ainsi a été enseignée la Viṣṇu-Gāyatrī, qui détruit tous les péchés. La syllabe sacrée ‘tāra’ (Oṁ) est le Seigneur dans le cœur, et elle est proclamée pour Vāsudeva.
Sanatkumara (teaching Narada in the Narada–Sanatkumara dialogue context)
Vrata: none
Primary Rasa: bhakti
Secondary Rasa: shanta
It identifies the Viṣṇu-Gāyatrī as a purifying mantra that removes sin, and links the primal syllable Oṁ (tāra) with the indwelling Lord, directing worship toward Vāsudeva.
Bhakti is expressed through mantra-upāsanā: remembering and proclaiming Vāsudeva with the Viṣṇu-Gāyatrī and Oṁ as the heart-centered presence of Bhagavān.
It highlights mantra-vidyā in a technical sense—proper identification of the mantra (Gāyatrī), its bīja/pranava (tāra/Oṁ), and its devatā (Vāsudeva) for disciplined japa and upāsanā.
