Sanatkumara (in instruction to Narada)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It teaches that mantra-japa is supported by nyāsa: the practitioner sanctifies the body by installing the mantra’s limbs, making the sādhana inwardly ordered and ritually complete.
Bhakti here is expressed as disciplined worship: the devotee honors the deity through correct mantra-limb placement (ṣaḍaṅga/nyāsa), treating the body-mind as a temple for the Lord’s mantra.
It reflects technical ritual procedure (mantra-śāstra/kalpa-style practice): ṣaḍaṅga-nyāsa, a structured placement beginning at hṛdaya and proceeding through prescribed aṅgas for accurate mantra application.
