When Śukadeva Gosvāmī finished describing the dynasty of Yadu, as well as the dynasties of the moon-god and sun-god, Mahārāja Parīkṣit requested him to describe Lord Kṛṣṇa, who appeared with Baladeva in the Yadu dynasty, and how Kṛṣṇa performed His activities within this world. Kṛṣṇa is transcendental, the King said, and therefore to understand His activities is the occupation of liberated persons. Hearing of kṛṣṇa-līlā is the boat by which to achieve the ultimate goal of life. Except for an animal killer or one who is following a policy of suicide, every intelligent person must strive to understand Kṛṣṇa and His activities.
