Objective Architecture

The keys to all the ancient arts are lost, were lost many centuries ago. And therefore there is no longer a sacred art embodying laws of the Great Knowledge, and so serving to influence the instincts of the multitude.

For instance, take architecture. I saw some examples of architecture in Persia and Turkey - for instance, one building of two rooms. Everyone who entered these rooms, whether old or young, whether English or Persian, wept. This happened with people of different backgrounds and education. We continued this experiment for two or three weeks and observed everyone's reactions. The result was always the same. We specially chose cheerful people. With these architectural combinations, the mathematically calculated vibrations contained in the building could not produce any other effect. We are under certain laws and cannot withstand external influences. Because the architect of this building had a different understanding and built mathematically, the result was always the same.

You come to a monastery. You are not a religious man, but what is played and sung there evokes in you a desire to pray. Later you will be surprised by this. And so it is with everyone. This objective art is based on laws, whereas modern music is entirely subjective. It is possible to prove where everything in this subjective art comes from.
