Mahāviṣṇu-Mantras: Aṣṭākṣarī, Sudarśana-Astra, Nyāsa Systems, Āvaraṇa-Pūjā, and Prayogas
ब्रह्मा मुनिः स्याद्गायत्री छन्दः प्रोक्तोऽथ देवता । पुरुषोत्तमसंज्ञोऽत्र बीजशक्तीस्मरंदिरे ॥ ८९ ॥
brahmā muniḥ syādgāyatrī chandaḥ prokto'tha devatā | puruṣottamasaṃjño'tra bījaśaktīsmaraṃdire || 89 ||
Ici, Brahmā est dit être le ṛṣi (le voyant) ; le mètre est déclaré être le Gāyatrī ; et la divinité présidante est nommée Puruṣottama. Dans (ce mantra), le bīja, la śakti et le smara (kīlaka/principe de verrou) doivent aussi être compris comme établis à leur juste place.
Narada (teaching in the Vedanga/technical-mantra context, within the Narada–Sanatkumara dialogue frame)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It formalizes mantra-vidhi by naming the ṛṣi (Brahmā), chandas (Gāyatrī), and devatā (Puruṣottama), showing that devotion and efficacy arise from correct Vedic identification and disciplined remembrance of the mantra’s inner powers (bīja–śakti–smara/kīlaka).
By stating Puruṣottama as the devatā, the verse directs the practitioner’s worship, meditation, and surrender toward Vishnu as the highest Person, while using precise mantra-structure to stabilize devotion.
It highlights technical mantra-science: determining ṛṣi, chandas, and devatā, along with bīja and śakti (and the smara/kīlaka principle), which are standard components used in nyāsa, japa, and ritual application.
