Weapon Type: Astra (mantric missile)
Concept: Body as kavaca (armor) through mantra-limbs; śakti is localized via nyāsa to protect and activate faculties (vision, vitality, resolve).
Application: Before japa/homa, perform ṣaḍaṅga-nyāsa to ‘seal’ the practice; use dvādaśāṅga when the mūla-mantra tradition prescribes expanded coverage.

It defines the ṣaḍaṅga-nyāsa mapping for bīja-mantras—heart, head, crown, armor, eyes, and astra—and notes that the mūla (root) mantra uses a more elaborate dvādaśāṅga (twelve-part) nyāsa.
