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.
Since Kṛṣṇa is all-attractive, one should know that all his desires should be focused on Kṛṣṇa. In the Bhagavad-gītā it is said that the individual person is the proprietor or master of his own body but that Kṛṣṇa, who is the Supersoul present in everyone's heart, is the supreme proprietor and supreme master of each and every individual body. As such, if we concentrate our loving propensities upon Kṛṣṇa only, then immediately universal love, unity and tranquillity will be automatically realized. When one waters the root of a tree, he automatically waters the branches, twigs, leaves and flowers; when one supplies food to the stomach through the mouth, he satisfies all the various parts of the body.
The art of focusing one's attention on the Supreme and giving one's love to Him is called Kṛṣṇa consciousness. We have inaugurated the Kṛṣṇa consciousness movement so that everyone can satisfy his propensity for loving others simply by directing his love toward Kṛṣṇa. The whole world is very eager to satisfy the dormant propensity of love for others, but the various invented methods like socialism, communism, altruism, humanitarianism and nationalism, along with whatever else may be manufactured for the peace and prosperity of the world, are all useless and frustrating because of our gross ignorance of the art of loving Kṛṣṇa. Generally people think that by advancing the cause of moral principles and religious rites they will be happy. Others may think that happiness can be achieved by economic development, and yet others think that simply by sense gratification they will be happy. But the real fact is that people can be happy only by loving Kṛṣṇa.
Kṛṣṇa can perfectly reciprocate one's loving propensities in different relationships called mellows, or rasas. Basically there are twelve loving relationships. One can love Kṛṣṇa as the supreme unknown, as the supreme master, the supreme friend, the supreme child, the supreme lover. These are the five basic love rasas. One can also love Kṛṣṇa indirectly in seven different relationships, which are apparently different from the five primary relationships. All in all, however, if one simply reposes his dormant loving propensity in Kṛṣṇa, then his life becomes successful. This is not a fiction but is a fact that can be realized by practical application. One can directly perceive the effects that love for Kṛṣṇa has on his life.
