In these few pages, I tried to find a connection between the structure of they pyramid and the structure of our souls. We are only curious about materialistic things in life, but after we leave this life we are not taking anything with us but our souls. The Great Pyramid is not a tomb. There was another reason such a magnificent building was constructed by the ancients for. I do believe they were trying to send a message to generations to come after. That is why I tried to link the ancient Greeks philosophy about number, the geometry of the pyramid and the knowledge we have so far in the field of psychology and wave structure and represent it to myself and to the reader in a simple way.
