All transcendental messages are received properly in the chain of disciplic succession. This disciplic succession is called paramparā. Unless therefore Bhāgavatam or any other Vedic literatures are received through the paramparā system, the reception of knowledge is not bona fide. Vyāsadeva delivered the message to Śukadeva Gosvāmī, and from Śukadeva Gosvāmī, Sūta Gosvāmī received the message. One should therefore receive the message of Bhāgavatam from Sūta Gosvāmī or from his representative and not from any irrelevant interpreter.
Emperor Parīkṣit received the information of his death in time, and he at once left his kingdom and family and sat down on the bank of the Ganges to fast till death. All great sages, ṛṣis, philosophers, mystics, etc., went there due to his imperial position. They offered many suggestions about his immediate duty, and at last it was settled that he would hear from Śukadeva Gosvāmī about Lord Kṛṣṇa. Thus the Bhāgavatam was spoken to him.
