The difference between science and mysticism is very light; the difference is only that one goes so far and the other goes farther still. Considering the idea of creation from a material point of view a scientist goes as far as realizing that there are certain elements which cause the creation, and form it into various objects. When he goes farther still, he goes as far as atoms, molecules, electrons, and then he comes to vibrations, and at this he stands still. He says that the basis of all creation must be movement, and the finest aspect of movement is called vibration. The mystic is not much different from the scientist who says that movement is at the basis of the whole creation. The difference is that the mystics of ancient times did not put a limit at the end, which they called movement or vibration: they traced the source in the divine Spirit.
