विन्यसेद्रृष्टिहर्तारं मूर्द्धांतं चरणादितः । न्यसेदंते ततो दिक्षु सर्वकार्यार्थसिद्धिदम् ॥ ९० ॥

自足起而上行至头顶,当为那位“除去有害目光”的神祇作安置(nyāsa)。随后于终了时,将(真言之力)安置于诸方;由此成就一切所愿与诸般仪轨事业。
Narada (teaching in a technical/ritual instruction sequence, within the Narada–Sanatkumara dialogue frame)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: vira
It teaches a protective and empowering nyāsa sequence—installing mantra-consciousness through the body (feet to crown) and then stabilizing it in the directions—so the practitioner becomes inwardly guarded and outwardly unobstructed in spiritual and worldly duties.
Although technical, it supports bhakti by prescribing embodied remembrance: the devotee ‘places’ the deity/mantra throughout the body and space, turning practice into continuous devotional presence that removes obstacles and strengthens focused worship.
A practical ritual-technology: nyāsa (body-installation) and dik-nyāsa (directional installation), commonly used in mantra-śāstra and temple/household rites to avert dr̥ṣṭi-doṣa and to secure sarva-kārya-siddhi (success in undertakings).
