We have seen many rich persons, many powerful persons, many famous persons, many beautiful persons, many learned and scholarly persons, and persons in the renounced order of life unattached to material possessions. But we have never seen any one person who is unlimitedly and simultaneously wealthy, powerful, famous, beautiful, wise and unattached, like Kṛṣṇa, in the history of humanity. Kṛṣṇa, the Supreme Personality of Godhead, is a historical person who appeared on this earth 5,000 years ago. He stayed on this earth for 125 years and played exactly like a human being, but His activities were unparalleled. From the very moment of His appearance to the moment of His disappearance, every one of His activities is unparalleled in the history of the world, and therefore anyone who knows what we mean by Godhead will accept Kṛṣṇa as the Supreme Personality of Godhead. No one is equal to the Godhead, and no one is greater than Him. That is the import of the familiar saying “God is great.
There are various classes of men in the world who speak of God in different ways, but according to the Vedic literature and according to the great ācāryas, the authorized persons versed in the knowledge of God in all ages, like ācāryas Śaṅkara, Rāmānuja, Madhva, Viṣṇu Svāmī, Lord Caitanya and all their followers by disciplic succession, all unanimously agree that Kṛṣṇa is the Supreme Personality of Godhead. As far as we, the followers of Vedic civilization, are concerned, we accept the Vedic history of the whole universe, which consists of different planetary systems, called Svargaloka, or the higher planetary system, Martyaloka, or the intermediary planetary system, and Pātālaloka, or the lower planetary system. The modern historians of this earth cannot supply historical evidences of events that occurred before 5,000 years ago, and the anthropologists say that 40,000 years ago Homo sapiens had not appeared on this planet because evolution had not reached that point. But the Vedic histories, such as the Purāṇas and Mahābhārata, relate human histories which extend millions and billions of years into the past.
For example, from these literatures we are given the histories of Kṛṣṇa’s appearances and disappearances millions and billions of years ago. In the Fourth Chapter of the Bhagavad-gītā Kṛṣṇa tells Arjuna that both He and Arjuna had had many births before and that He (Kṛṣṇa) could remember all of them but Arjuna could not. This illustrates the difference between the knowledge of Kṛṣṇa and that of Arjuna. Arjuna might have been a very great warrior, a well-cultured member of the Kuru dynasty, but after all, he was an ordinary human being, whereas Kṛṣṇa, the Supreme Personality of Godhead, is the possessor of unlimited knowledge. Because He possesses unlimited knowledge, Kṛṣṇa has a memory that is boundless.
The knowledge Kṛṣṇa possesses is so perfect that He remembers all the incidents of His appearances some millions and billions of years in the past, but Arjuna’s memory and knowledge are limited by time and space, for he is an ordinary human being. In the Fourth Chapter Kṛṣṇa states that He can remember instructing the lessons of the Bhagavad-gītā some millions of years ago to the sun-god, Vivasvān.
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.
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.
