It highlights that correct knowledge of language—especially verb-forms used in Vedic recitation—supports precision in dharma and the disciplined pursuit of moksha, because mantra and teaching are transmitted through exact speech.
Indirectly: bhakti practices depend on accurate chanting and comprehension; this verse models the Vedanga approach that safeguards devotional recitation by teaching correct grammatical forms.
Vedanga—Vyakarana (grammar): it lists standard conjugational/derivational forms (present, perfect, aorist, future, imperative, optative, agent noun) as memorisable paradigms for correct usage in study and recitation.
