Nyāsa, Yantra, Homa, and Dīpa-Vrata
स्वबीजानंगध्रुववाक्कर्णिकं दिग्दलं लिखेत् । तारादिवर्मांतदलं शेषवर्णदलांतरम् ॥ २५ ॥
svabījānaṃgadhruvavākkarṇikaṃ digdalaṃ likhet | tārādivarmāṃtadalaṃ śeṣavarṇadalāṃtaram || 25 ||
Debe inscribirse en el pericarpio central (karṇikā) la sílaba-semilla (bīja) propia, junto con los aṅga-mantras, la fórmula fija (dhruva) y el mantra de la palabra (vāk). Luego se trazan los pétalos según las direcciones. En los pétalos se escribe la serie desde Tārā hasta Varma; y en los espacios entre pétalos, las sílabas restantes.

It teaches the disciplined, rule-based placement of mantras on a lotus-yantra—centering the practice on the bīja and protective formulas so the sādhaka’s worship becomes orderly, guarded (varma), and focused.
Though technical, it supports bhakti by prescribing a precise worship-layout: mantra placement (karṇikā, petals, interspaces) becomes a concrete method to concentrate the mind on the deity through regulated japa, nyāsa, and protection-mantras.
It highlights ritual-technical know-how—mantra-lekhana and nyāsa-style arrangement (aṅga, dhruva, varma) with directional mapping—typical of the Narada Purana’s Vedāṅga/technical-science orientation in Book 1.3.
