The rapid changes of the mind and the elements of the body have been explained in Buddhism. According to the Buddha in every fraction of a split second the mind appears and disappears. Biology, physiology and psychology also teach the same nature of changes in life. Therefore life is not static.
Psychologist Prof. William James has explained the point-moment of consciousness. He discussed how consciousness comes into being and passes away again in rapid succession.
According to the nature that causes the continuous process of mind, as soon as a mind is born, it gives birth to another mind and dies. The mind is born in turn gives birth to another mind and dies, and so on.
To the question how evil thoughts appeared in man's mind at the beginning, the cause of those evil thoughts is selfish motives which exist due to craving for existence and in his belief in a permanent ego that constantly craves satisfaction of the senses.
When we study the life and the teachings of the Buddha we can see that everything is open to everybody. There are no secret doctrines.
The events that took place during his whole life were open and there were no hidden and mystical incidents. In the eyes of the Buddha, so-called supernatural powers to many people are not supernatural but only natural phenomena which the ordinary man cannot comprehend. As man's knowledge and understanding of the universe increases his belief in the supernatural decreases. To primitive man "thunder and lightning" were manifestations of angry gods. Today, we know they are merely electrical charges.
If the component things are subject to the natural laws of change, decay and death, how can we introduce them as supernatural powers?
Even the Buddha's birth, enlightenment and death took place openly. He lived as a normal religious teacher and as a real human being.
The Buddha has pointed out the process of evolving from the animal life into human status and from human status into the divine state. Divine life proceeds to the Brahma state and Brahma life into perfect life. One can also proceed from a noble pure life into a perfect holy life. The Buddha has pointed out the reverse order as well, that is, going from human life into animal life.
