रम्योपवनपर्यन्ते स तस्मिन् पार्थिवोत्तम निदाघो नाम योगज्ञ ऋभुशिष्यो ऽवसत् पुरा

O best of kings, in that very place—at the edge of a delightful grove—there once dwelt Nidāgha, a knower of Yoga, the disciple of Ṛbhu, in former times.
Sage Parāśara (narrating to Maitreya)
Bhakti Type: Shanta
It frames Nidāgha as an accomplished practitioner of inner discipline, preparing the reader for a teaching-story where true knowledge is shown to be inward (discernment and freedom from identification), not merely external ritual or status.
By identifying Nidāgha as Ṛbhu’s disciple, the Purana signals that liberating insight is transmitted through a living lineage—where instruction, testing, and direct realization unfold through dialogue and guidance.
Even when Vishnu is not named in the verse, the Purana’s aim is to orient Yoga and knowledge toward the Supreme Reality—Vishnu as the highest principle—so that renunciation and discernment culminate in God-centered liberation rather than mere philosophical abstraction.
