Mahārāja Parīkṣit very much appreciated Kṛṣṇa's activities for many other reasons. Not only was his grandfather saved by Kṛṣṇa, but he himself also was saved by Kṛṣṇa. By the end of the Battle of Kurukṣetra, all the members of the Kuru dynasty, both the sons and grandsons on the side of Dhṛtarāṣṭra and those on the side of the Pāṇḍavas, had died in the fighting. Except the five Pāṇḍava brothers, everyone died on the Battlefield of Kurukṣetra. Mahārāja Parīkṣit was at that time within the womb of his mother. His father, Abhimanyu, the son of Arjuna, also died on the Battlefield of Kurukṣetra, and so Mahārāja Parīkṣit was a posthumous child. When he was in the womb of his mother, a brahmāstra weapon was released by Aśvatthāmā to kill the child. When Parīkṣit Mahārāja's mother, Uttarā, approached Kṛṣṇa, Kṛṣṇa, seeing the danger of abortion, entered her womb as the Supersoul and saved Mahārāja Parīkṣit. Mahārāja Parīkṣit's other name is Viṣṇurāta because he was saved by Lord Viṣṇu Himself while still within the womb.
Thus everyone, in any condition of life, should be interested in hearing about Kṛṣṇa and His activities because He is the Supreme Absolute Truth, the Personality of Godhead. He is all-pervading: inside He is living within everyone's heart, and outside He is living as His universal form. And yet, as described in the Bhagavad-gītā, He appears as He is in the human society just to invite everyone to His transcendental abode, back home, back to Godhead. Everyone should be interested in knowing about Kṛṣṇa, and this book is presented with this purpose: that people may know about Kṛṣṇa and be perfectly benefited in this human form of life.
