It teaches mantra-based protection through nyāsa: sacred sound is consciously placed on key bodily centers to guard the practitioner and stabilize the rite.
Though technical, it supports devotion by safeguarding worship: the devotee uses mantra-protection so the mind and senses remain steady for focused remembrance and worship.
Ritual procedure (prayoga) and mantra-application (nyāsa/anga-nyāsa) are highlighted—how to utter bija-like exclamations such as “hum” and place protection on specific body points.
