Geometry and sacred geometry have been mentioned since ancient times. Sacred geometry is used in design, architecture and art. The underlying belief is that geometry, logico-mathematical series, harmony and proportions are all found in music, light, the human body and cosmology. The link between mathematics, geometry and music was exposed by Pythagoras already.
Colour and sound are related and are expressions of the soul. Each thought and each tone has its colour shade, its code, its expressive value. Science, too, deals with colours and their influence on man. We often forget the importance of what colour or sound surround us. With a conscious choice of these elements we can improve our daily surroundings, our mood and the state of our spirit.
