yad aha no bhavan suta
cacara tirthani bhuvas
tyaktva bandhun sudustyajan
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Saunaka Rsi, after hearing all about the creation, inquired from Suta Gosvami about Vidura, for Suta Gosvami had previously informed him how Vidura left home, leaving aside all his relatives, who were very difficult to leave.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada :
The rsis headed by Saunaka were more anxious to know about Vidura, who met Maitreya Rsi while traveling to the pilgrimage sites of the world.
