The religions of the old Egyptians, of the ancient Greeks, of the Hindus, and of the Parsis, all have symbols which express the essential Truth hidden under a religion. There is a symbolism in Christianity, and in many ancient religions of the world. Man has often rebelled against symbolism; but it is natural: man has always revolted against things he cannot understand. There has been a wave of opposition to symbolism in both parts of the world, the East and the West. It came in the East in the period of Islam, and in the West it re-echoed in the Reformation. No doubt when the sacred symbols are made as patents by the religious who want to monopolize the whole Truth for themselves, then it gives rise to that tendency of human nature which is always ready to accept things or reject them. However, one can say without exaggeration that symbology has always served to keep the ancient wisdom intact for ages. It is symbology that can prove today the saying of Solomon: "There is nothing new under the sun." There are many thoughts relating to human nature, the nature of life, relating to God and His many attributes, and relating to the path towards the goal, that are expressed in symbolism.
