This kṛṣṇa-kathā will also be very much appealing to the most materialistic persons because Kṛṣṇa’s pastimes with the gopīs (cowherd girls) are exactly like the loving affairs between young girls and boys within this material world. Actually, the sex feeling found in human society is not unnatural because this same sex feeling is there in the original Personality of Godhead. The pleasure potency is called Śrīmatī Rādhārāṇī. The attraction of loving affairs on the basis of sex feeling is the original feature of the Supreme Personality of Godhead, and we, the conditioned souls, being part and parcel of the Supreme, have such feelings also, but they are experienced within a perverted, minute condition. Therefore, when those who are after sex life in this material world hear about Kṛṣṇa’s pastimes with the gopīs, they will relish transcendental pleasure, although it appears to be materialistic. The advantage will be that they will gradually be elevated to the spiritual platform. In the Bhāgavatam it is stated that if one hears the pastimes of Lord Kṛṣṇa with the gopīs, from authorities with submission, then he will be promoted to the platform of transcendental loving service to the Lord, and the material disease of lust within his heart will be completely vanquished. In other words, such hearing will counteract material sex life.
This book, Kṛṣṇa, which is filled with kṛṣṇa-kathā, will thus appeal equally to the liberated souls and to persons who are trying to be liberated, as well as to the gross, conditioned materialist. According to the statement of Mahārāja Parīkṣit, who heard about Kṛṣṇa from Śukadeva Gosvāmī, kṛṣṇa-kathā is equally applicable to every human being, whatever condition of life he is in. Surely everyone will appreciate it to the highest magnitude. But Mahārāja Parīkṣit also warned that persons who are simply engaged in killing animals and in killing themselves may not be very much attracted to kṛṣṇa-kathā. In other words, ordinary persons who are following the regulative moral principles of scriptures, no matter in what condition they are found, will certainly be attracted, but not persons who are killing themselves. The exact word used in Śrīmad-Bhāgavatam is paśu-ghna, which means killing animals or killing oneself. Persons who are not self-realized and who are not interested in spiritual realization are killing themselves; they are committing suicide. Because this human form of life is especially meant for self-realization, by neglecting this important part of his activities one simply wastes his time like the animals. So he is paśu-ghna. The other meaning of the word refers to those who are actually killing animals. This means persons who are animal-eaters (even dog-eaters), for they are all engaged in killing animals in so many ways, such as hunting and opening slaughterhouses. Such persons cannot be interested in kṛṣṇa-kathā.
King Parīkṣit was especially interested in hearing kṛṣṇa-kathā because he knew that his forefathers, particularly his grandfather, Arjuna, were victorious in the great Battle of Kurukṣetra only because of Kṛṣṇa. We may also take this material world as a Battlefield of Kurukṣetra. Everyone is struggling hard for existence on this battlefield, and at every step there is danger. According to Mahārāja Parīkṣit, the Battlefield of Kurukṣetra was just like a vast ocean full of dangerous animals. His grandfather Arjuna had to fight with such great heroes as Bhīṣma, Droṇa, Karṇa and many others who were not ordinary fighters. Such warriors have been compared to the timiṅgila fish in the ocean. The timiṅgila fish can very easily swallow up big whales. The great fighters on the Battlefield of Kurukṣetra could swallow many, many Arjunas very easily, but simply due to Kṛṣṇa’s mercy, Arjuna was able to kill all of them. Just as one can cross with no exertion over the little bit of water contained in the hoofprint of a calf, so Arjuna, by the grace of Kṛṣṇa, was able to very easily jump over the ocean of the Battle of Kurukṣetra.
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.
