ब्रह्मा मुनिः स्याद्गायत्री छन्दः प्रोक्तोऽथ देवता । पुरुषोत्तमसंज्ञोऽत्र बीजशक्तीस्मरंदिरे ॥ ८९ ॥
brahmā muniḥ syādgāyatrī chandaḥ prokto'tha devatā | puruṣottamasaṃjño'tra bījaśaktīsmaraṃdire || 89 ||
ইয়াত ব্ৰহ্মা ঋষি (মুনি) বুলি কোৱা হৈছে; ছন্দ গায়ত্ৰী বুলি প্ৰোক্ত; আৰু অধিদেৱতা ‘পুৰুষোত্তম’ নামে উক্ত। এই মন্ত্ৰত বীজ, শক্তি আৰু স্মৰ (কীলক)ও নিজ নিজ স্থানত প্ৰতিষ্ঠিত বুলি বুজিব লাগে।
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.
