ऋभु–निदाघ-संवादः—अद्वैत-उपदेशः, समता, वासुदेव-स्वरूप-एकत्वम्
अवाप्तज्ञानतत्त्वस्य न तस्याद्वैतवासनाम् स ऋभुस् तर्कयाम् आस निदाघस्य नरेश्वर
avāptajñānatattvasya na tasyādvaitavāsanām sa ṛbhus tarkayām āsa nidāghasya nareśvara
O king, although Nidāgha had grasped the principle of true knowledge, the inward inclination toward non-duality had not yet arisen in him; therefore Ṛbhu began to guide Nidāgha through discerning reasoning.
Sage Parāśara (narrating to Maitreya)
Speaker: Parasara
Topic: Why reasoning was needed despite Nidāgha’s learning—absence of advaita-vāsanā
Teaching: Philosophical
Quality: analytical
Concept: Conceptual knowledge of truth is incomplete without deep inner assimilation (vāsanā) that stabilizes non-dual insight.
Vedantic Theme: Moksha
Application: Move from study to sustained contemplation: observe identification with body/mind, practice neti-neti discernment, and cultivate steady inner witnessing.
Vishishtadvaita: Even when ‘non-duality’ language appears, the Purāṇic pedagogy can be read as removing false separations while preserving the Supreme as the true ground of all—supporting qualified non-dualism rather than impersonal monism.
Vishnu Form: Para-Brahman
Bhakti Type: shanta
This verse distinguishes mere understanding of truth from the deep inner conditioning that makes realization stable; liberation requires the ripening of such inward disposition, not only conceptual knowledge.
Here, reasoning is presented as Ṛbhu’s tool to move the disciple from intellectual grasp to transformative insight—clarifying confusion until the mind naturally inclines toward the highest truth.
Even when the verse discusses non-duality and knowledge, the Vishnu Purana frames ultimate truth as grounded in the Supreme Reality of Vishnu; realization is not abstract but oriented toward the highest principle the Purana identifies with Vishnu.
