Spiritual science teaches of the existence of certain highly evolved men, the initiates, and it has been taught in the Mystery Schools of all times how man can bring himself to such a stage of evolution. Definite exercises were prescribed there which develop man in quite a natural way. They are exercises of meditation and concentration which are to give man another kind of sight which cannot be attained with the intellect and the five senses. Meditation in the first place leads away from the grasp of the senses. Through inner soul-work man becomes free of the senses. Something then takes place similar to the operation on a man born blind. There is a kind of operation which opens man’s spiritual eyes and ears. It will be attained in the development of the whole human race in the course of a long period of time. But one must not disclaim the world when one wishes to rise higher; an ascetic fleeing from the world does not serve clairvoyance. Clairvoyance is the fruit of what the soul collects in the sense-world. Greek philosophy beautifully compared the human soul with a bee. The world of colour and light offers the soul honey which it brings with it into the higher world. The soul must spiritualise sense experience and carry it up into higher worlds.
