The act of understanding occurs in one person when the communication comes from the created element in another person. When it comes from the uncreated it is not understood either in the individual himself or in the other. Yet there is something in the interpersonal communication which is able to transform the uncreated into the created. Belief is that psychological transformer which changes possibility into reality. It is the hen sitting on an egg. The egg has the possibility of becoming a baby chicken. The broody hen sitting on the egg enables the egg to become a baby chicken. Belief is of this nature. It can be in error. A hen can sit and sit on an unfertilised egg and no chick will ever appear. The element has to be capable of being transformed. Belief in the personality functions to bring about the transformation.
