Indirectly: bhakti practices rely on accurate mantra, nāma, and śāstra-recitation; this verse reinforces that proper linguistic understanding preserves the integrity of Vedic sound used in worship and devotion.
Vyākaraṇa (grammar): it notes vibhāṣā (optional rules/variants) and identifies bhū-ādi verbal roots as parasmaipada, a practical rule for correct conjugation in Vedic and śāstric usage.
