Rudolf Steiner: "The esotericist uses words to make us aware of how the spirit in its reality streams in upon us and wants to pour itself into the hearts of human beings. Therefore in an esoteric school it is necessary for the pupil over time to develop an inner sense of listening to what lies behind the words. When this inner sense is developed with respect to esotericism, we will acquire what has been held sacred in esoteric streams throughout the ages: namely, the power of silence, the sacred power of silence.... Esotericism first has to live in the wordless weaving of the soul before it can be regarded as fully mature."
