In the middle of the brain is the so-called "magic eye of the soul" or "inner sun of man." If this sun is not shining in man, nothing becomes of him. It acts as a transformer in the human body. When external energy enters the brain, this node or the eye of the soul forwards this energy throughout the brain. It has other properties in addition to transform solar energy.
In the brain there is another transformer which forwards solar energy throughout the body. The healthy state of both the body and the senses depends on the correct transformation of these energies. So this eye is the transformer of the Divine energy in man and creates conditions for its manifestation. When the Sun shines inside man, he is joyful and glad.
