It teaches that mantra-nyāsa is not merely recitation but an internalization—installing the mantra in key sense-and-awareness centers to awaken devatā-bhāva (the felt presence/identity with the deity).
By directing the practitioner to embody the deity through mantra-nyāsa, it supports bhakti as lived remembrance—making perception (eyes, ears) and consciousness (head/ājñā) instruments of continual devotion.
It highlights a technical upāsanā method used in ritual manuals—nyāsa (mantra placement) as a disciplined procedure connected to mantra-prayoga and śāstra-based ritual science.
