The external instruments get hold of the impressions and carry them to the organs, for you must remember always, that the eyes and ears are only receivers — it is the internal organs, the brain centres, which act. In Sanskrit these centres are called Indriyas, and they carry sensations to the mind, and the mind presents them further back to another state of the mind, which in Sanskrit is called Chitta, and there they are organised into will, and all these present them to the King of kings inside, the Ruler on His throne, the Self of man. He then sees and gives His orders. Then the mind immediately acts on the organs, and the organs on the external body. The real Perceiver, the real Ruler, the Governor, the Creator, the Manipulator of all this, is the Self of man.
