It shows that the Purana preserves Vedanga knowledge (especially Vyakarana) so seekers can interpret dharma and moksha teachings precisely; correct meaning in scripture depends on correct grammatical usage.
Indirectly: by safeguarding accurate comprehension of sacred statements, grammar supports right understanding of Vishnu-bhakti instructions; devotion becomes steady when scripture is understood without ambiguity.
Vyakarana: rules for when the instrumental (tṛtīyā) expresses association, when the locative (saptamī) indicates time or state, and how the genitive (ṣaṣṭhī) can also appear in related constructions.
