Fear can exist only in relationship; fear cannot exist by itself, in isolation. There is no such thing as abstract fear; there is fear of the known or the unknown, fear of what one has done or what one may do; fear of the past or of the future. The relationship between what one is and what one desires to be causes fear. Fear arises when one interprets the fact of what one is in terms of reward and punishment. Fear comes with responsibility and the desire to be free from it. There is fear in the contrast between pain and pleasure. Fear exists in the conflict of the opposites. The worship of success brings the fear of failure. Fear is the process of the mind in the struggle of becoming. In becoming good, there is the fear of evil; in becoming complete, there is the fear of loneliness; in becoming great, there is the fear of being small. Comparison is not understanding; it is prompted by fear of the unknown in relation to the known. Fear is uncertainty in search of security.
