Those who have probed the depth of material science as far as modern science can reach, do not deny the fact that the origin of the whole creation is in movement, in other words: in vibration. It is this original state of the existence of life which is called in the ancient tradition sound, or the word. The first manifestation of this sound is therefore audible, the next manifestation visible. In the forms of expression of life, life has expressed itself first as sound, next as light. This is supported by the Bible where it is said that first was the word, and then came light. Again one finds in a Sura of the Qur'an: "God is the light of the heaven and the earth."
