Narada (teaching in a technical/ritual context within the Vedanga-oriented section)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It prescribes an internal nyāsa sequence that sacralizes key bodily centers, turning the body into a fit locus for mantra—progressing from lower support to the crown (brahma-randhra) to refine awareness upward.
While technical, the ordered nyāsa supports bhakti by steadying mind and prāṇa so that japa and remembrance of the deity can be performed with one-pointed devotion.
It reflects applied ritual-technical discipline (prayoga) akin to Vedāṅga-oriented procedure—precise bodily placements (nyāsa) used to empower mantra recitation and meditative focus.
