Weapon Type: Astra (protective missile-mantra)
Concept: Somatic sacralization: mantra is installed progressively to integrate cognition (head/eyes), vitality (heart/abdomen), and action (limbs/feet).
Application: Use a consistent order each sitting; synchronize touch, visualization, and bīja utterance to avoid ‘broken’ nyāsa (khaṇḍa-nyāsa) and to strengthen protective intent.

It teaches the nyāsa-krama—sequentially installing protective mantras (heart, head, śikhā, kavaca, astra, and then limbs) to create a ritual ‘armor’ over the practitioner’s body.
Beyond mythology, the Agni Purana preserves practical ritual technology—precise bodily placements and protective formulae—showing it functions as a manual of applied mantra-śāstra alongside other sciences.
Nyāsa sacralizes the body as a fit vessel for worship, seals the directions/limbs against impediments, and is traditionally held to enhance purity, concentration, and protective merit during sādhana.
