Vyāsadeva himself was the disciple of Nāradajī, and therefore it was natural to be anxious to hear what Nārada did after initiation from the spiritual masters. He wanted to follow in Nārada’s footsteps in order to attain to the same perfect stage of life. This desire to inquire from the spiritual master is an essential factor to the progressive path. This process is technically known as sad-dharma-pṛcchā.
