It emphasizes Vedanga mastery—especially Vyakarana—as a support for dharma and moksha: correct linguistic form protects the intended meaning of mantra, scripture, and teaching.
Indirectly: Bhakti practices rely on accurate names, mantras, and recitations; this technical rule safeguards purity of utterance so devotion is expressed without distortion.
Vyakarana: a sutra-like rule about when certain grammatical markers/augments are considered elided (nihata) under specified root/affix conditions, aiding correct derivation and recitation.
