Narada (in instructional dialogue, traditionally framed within Narada–Sanatkumara discourse)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: bhakti
It teaches disciplined mantra-prayoga: the power of a mantra is stabilized through precise nyāsa (ritual placement), aligning speech, body, and intention so the deity-invocation becomes inwardly established.
Although technical, the procedure supports bhakti by making worship methodical—recitation is not merely verbal, but a reverent installation of the Lord’s mantra in one’s limbs/regions, cultivating focused devotion.
It reflects applied ritual science—mantra-prayoga and nyāsa conventions (often discussed alongside Śikṣā for pronunciation and Kalpa-style procedure), including the use of bīja-syllables like “huṃ” and comprehensive placements such as ‘sarvapada’.
