Buddhism does not totally deny the existence of a personality in an empirical sense. It only attempts to show that it does not exist in an ultimate sense. The Buddhist philosophical term for an individual is Santana, i.e., a flux or a continuity. It includes the mental and physical elements as well. The Kammic force of each individual binds the elements together. This uninterrupted flux or continuity of psycho-physical phenomenon, which is conditioned by Kamma, and not limited only to the present life, but having its source in the beginningless past and its continuation in the future — is the Buddhist substitute for the permanent ego or the immortal soul of other religions.

The Buddha Dhamma is not based on the fear of the unknown, but is founded on the bedrock of facts which can be tested by ourselves and verified by experience. Buddhism is, therefore rational and intensely practical. Such a rational and practical system cannot contain mysteries or esoteric doctrines. Blind faith, therefore, is foreign to Buddhism. Where there is no blind faith there cannot be any coercion or persecution or fanaticism. To the unique credit of Buddhism it must be said that throughout its peaceful march of 2500 years no drop of blood was shed in the name of the Buddha, no mighty monarch wielded his powerful sword to propagate the Dhamma, and no conversion was made either by force or by repulsive methods. Yet, the Buddha was the first and the greatest missionary that lived on earth.

Surely "the doctrine that all men are sinners and have the essential sin of Adam is a challenge to justice, mercy, love and omnipotent fairness." Some writers of old authoritatively declared that God created man in his own image. Some modern thinkers state, on the contrary, that man created God in his own image. With the growth of civilization man's concept of God also became more and more refined. It is however, impossible to conceive of such a being either in or outside the universe. Could this variation be due to heredity and environment? One must admit that all such chemico-physical phenomena revealed by scientists, are partly instrumental, but they cannot be solely responsible for the subtle distinctions and vast differences that exist amongst individuals. Yet why should identical twins who are physically alike, inheriting like genes, enjoying the same privilege of upbringing, be very often temperamentally, morally and intellectually totally different? Heredity alone cannot account for these vast differences. Strictly speaking, it accounts more plausibly for their similarities than for most of the differences. … With regard to the more complex and subtle mental, intellectual and moral differences we need more enlightenment. The theory of heredity cannot give a satisfactory explanation for the birth of a criminal in a long line of honourable ancestors, the birth of a saint or a noble man in a family of evil repute, for the arising of infant prodigies, men of genius and great religious teachers. According to Buddhism this variation is due not only to heredity, environment, "nature and nurture," but also to our own kamma, or in other words, to the result of our own inherited past actions and our present deeds. We build our own hells. We create our own heavens. We are the architects of our own fate. In short we ourselves are our own kamma.
