Sanatkumara (teaching Narada)
Vrata: none
Primary Rasa: shanta

It maps specific inner loci where attention is to be stabilized so that nāda (subtle sound) becomes a support for nirodha (restraint), leading the mind toward steadiness and liberation-oriented absorption.
While primarily yogic/technical, it supports bhakti indirectly by training one-pointedness; a steadied mind can hold divine remembrance without distraction, making devotion continuous and deeper.
This belongs to the technical-yogic instruction stream associated with Vedāṅga-style disciplines (especially Śikṣā and subtle phonetics of sound), using nāda as a practical method of concentration.
