Vyākaraṇa-saṅgraha: Pada–Vibhakti–Kāraka–Lakāra–Samāsa
स्वामीश्वरोधिपतिभिः साक्षिदायादसूतकैः । निर्धारणे द्वे विभक्ती षष्टी हेतुप्रयोगके ॥ १५ ॥
svāmīśvarodhipatibhiḥ sākṣidāyādasūtakaiḥ | nirdhāraṇe dve vibhaktī ṣaṣṭī hetuprayogake || 15 ||
With words such as “svāmī” (master), “īśvara” (Lord), “adhipati” (overlord), “sākṣī” (witness), “dāyāda” (heir), and “sūtaka” (one under ritual impurity), two case-endings are used in expressions of specification (nirdhāraṇa); but in causal usage the sixth case, the genitive (ṣaṣṭhī), is employed.

It shows that Moksha-dharma instruction in the Narada Purana includes disciplined speech (śabda-śuddhi): correct grammatical usage supports clarity in dharma and scriptural understanding.
Indirectly: bhakti is nourished by accurate comprehension of śāstra; this verse emphasizes linguistic precision so that teachings about God, duty, and purity are not misunderstood.
Vyākaraṇa (grammar): it notes case-governance—certain nouns allow two vibhaktis in specification, while genitive (ṣaṣṭhī) is used when expressing a cause (hetu-prayoga).
