Narada (teaching within a technical/Vedanga-style enumeration)
Vrata: none
Primary Rasa: adbhuta
Secondary Rasa: bhakti
It links divine forms (Nṛsiṃha, Nārāyaṇa) with energetic principles (a sustaining ‘flow’ and lightning-like radiance) and anchors them in the Keśavādi Mātr̥kā, implying that sacred sound/phonemes are a vehicle for realizing Vishnu’s presence.
By identifying the sage-principle with Nārāyaṇa within the Keśava-based sacred sound matrix, it supports Bhakti through nāma (divine names) and mantra—devotion expressed as remembrance, recitation, and contemplative alignment with Vishnu’s forms.
It reflects a technical mantra/phoneme framework (Mātr̥kā), aligning with Śikṣā and Vyākaraṇa-oriented thinking—how sound-units and name-sequences are systematically mapped to deities for japa, nyāsa, and ritual application.
