Sūta said: O brāhmaṇas, thus hearing all about Śrī Nārada’s birth and activities, Vyāsadeva, the incarnation of God and son of Satyavatī, inquired as follows.
Purport: 

Vyāsadeva was further inquisitive to know about the perfection of Nāradajī, and therefore he wanted to know about him more and more. In this chapter Nāradajī will describe how he was able to have a brief audience with the Lord while he was absorbed in the transcendental thought of separation from the Lord and when it was very painful for him.
