Translation: 
Śaunaka Ṛṣi, after hearing all about the creation, inquired from Sūta Gosvāmī about Vidura, for Sūta Gosvāmī had previously informed him how Vidura left home, leaving aside all his relatives, who were very difficult to leave.
Purport: 

The ṛṣis headed by Śaunaka were more anxious to know about Vidura, who met Maitreya Ṛṣi while traveling to the pilgrimage sites of the world.
