एवम् उक्त्वा ययौ विद्वान् निदाघं स ऋभुर् गुरुः निदाघो ऽप्य् उपदेशेन तेनाद्वैतपरो ऽभवत्
evam uktvā yayau vidvān nidāghaṃ sa ṛbhur guruḥ nidāgho 'py upadeśena tenādvaitaparo 'bhavat
Having spoken thus, the wise guru Ṛbhu departed from Nidāgha; and Nidāgha too—through that very instruction—became devoted to the realization of non-duality.
Sage Parāśara (narrating to Maitreya)
Concept: A concise instruction, once received, transforms the disciple’s orientation toward non-dual realization.
Vedantic Theme: Atman
Application: After receiving guidance, prioritize sustained practice and reflection so the teaching becomes lived insight, not only memory.
Vishishtadvaita: Stresses disciplined assimilation (nididhyāsana-like ripening) after śravaṇa/upadeśa—compatible with Vaiṣṇava sādhanā culminating in God-realization.
Vishnu Form: Para-Brahman
Bhakti Type: Shanta
It marks the culmination of the guru’s instruction: Nidāgha’s mind turns from external distinctions to the vision of a single underlying reality, a key mokṣa-oriented teaching in this dialogue.
By presenting a direct cause-and-effect: Ṛbhu’s teaching is sufficient to transform Nidāgha’s orientation, showing that right knowledge transmitted through the guru-disciple relationship leads toward liberation.
Even when the verse speaks in non-dual terms, the Vishnu Purana’s broader frame treats the highest reality as the supreme principle identified with Vishnu—knowledge ultimately resolves into the recognition of that supreme truth.
