According to Buddhism mind is nothing but a complex compound of fleeting mental states. One unit of consciousness consists of three phases — arising or genesis (uppada) static or development (thiti), and cessation or dissolution (bhanga). Immediately after the cessation stage of a thought moment there occurs the genesis stage of the subsequent thought-moment. Each momentary consciousness of this ever-changing life-process, on passing away, transmits its whole energy, all the indelibly recorded impressions to its successor. Every fresh consciousness consists of the potentialities of its predecessors together with something more. There is therefore, a continuous flow of consciousness like a stream without any interruption. The subsequent thought moment is neither absolutely the same as its predecessor — since that which goes to make it up is not identical — nor entirely another — being the same continuity of Kamma energy. Here there is no identical being but there is an identity in process. Every moment there is birth, every moment there is death. The arising of one thought-moment means the passing away of another thought-moment and vice versa. In the course of one life-time there is momentary rebirth without a soul. It must not be understood that a consciousness is chopped up in bits and joined together like a train or a chain. But, on the contrary, "it persistently flows on like a river receiving from the tributary streams of sense constant accretions to its flood, and ever dispensing to the world without the thought-stuff it has gathered by the way."

It should be mentioned that any external supernatural agency plays no part whatever in the moulding of the character of a Buddhist. In Buddhism there is no one to reward or punish. Pain or happiness are the inevitable results of one's actions. The question of incurring the pleasure or displeasure of a God does not enter the mind of a Buddhist. Neither hope of reward nor fear of punishment acts as an incentive to him to do good or to refrain from evil. A Buddhist is aware of future consequences, but he refrains from evil because it retards, does good because it aids progress to Enlightenment (Bodhi). There are also some who do good because it is good, refrain from evil because it is bad.

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.
