Nowadays it is the fashion of the atheistic class of men to try to become God by following some mystic process. Generally the atheists claim to be God by dint of their imagination or their meditational prowess. Kṛṣṇa is not that kind of God. He does not become God by manufacturing some mystic process of meditation, nor does He become God by undergoing the severe austerities of the mystic yogic exercises. Properly speaking, He never becomes God because He is the Godhead in all circumstances.
Within the prison of His maternal uncle Kaṁsa, where His father and mother were confined, Kṛṣṇa appeared outside His mother's body as the four-handed Viṣṇu-Nārāyaṇa. Then He turned Himself into a baby and told His father to carry Him to the house of Nanda Mahārāja and his wife Yaśodā. When Kṛṣṇa was just a small baby the gigantic demoness Pūtanā attempted to kill Him, but when He sucked her breast He pulled out her life. That is the difference between the real Godhead and a God manufactured in the mystic factory. Kṛṣṇa had no chance to practice the mystic yoga process, yet He manifested Himself as the Supreme Personality of Godhead at every step, from infancy to childhood, from childhood to boyhood, and from boyhood to young manhood. In this book, Kṛṣṇa, all of His activities as a human being are described. Although Kṛṣṇa plays like a human being, He always maintains His identity as the Supreme Personality of Godhead.
