A symbol is a term or a picture that may be familiar in daily life, yet possessing specific connotations in addition to its obvious meaning. It implies something vague or hidden from us. Thus, a word or an image is symbolic when it implies something more than its immediate meaning. It has a wider “unconscious” aspect that is never precisely defined or fully explained. As the mind explores the symbol, it is led to ideas that lie beyond the grasp of reason. Since there are many things beyond the range of human understanding, we use symbolic terms to represent concepts that we cannot define or fully comprehend. This is one reason why historically all religions have employed symbolic language or images. However, this conscious use of symbols is only one aspect of a psychological fact of great importance. Man also produces symbols unconsciously and spontaneously, in the form of dreams. It is not easy to grasp this point, but we must if we are to know more about the ways in which the human mind works.
