Sanatkumara (teaching Narada in a Vedanga/śāstra context)
Vrata: none
Primary Rasa: shanta
Secondary Rasa: none
It frames śāstra as both rule-governed and usage-aware: disciplined learning (especially Vedāṅgas like Vyākaraṇa and Śikṣā) supports clarity in Vedic study, which in turn aids right understanding on the path of dharma and mokṣa.
Indirectly: accurate speech, chanting, and comprehension depend on grammar and accent; such correctness strengthens mantra-recitation and scriptural hearing (śravaṇa), which are foundational supports for sustained Viṣṇu-bhakti even when the verse itself is technical.
Vyākaraṇa and Śikṣā: it notes that grammatical authorities may allow substitutions and irregular forms, and that these can be accepted when backed by prevalent usage (bāhulaka), including matters of endings (suP/tiṅ) and Vedic accent (svara).
