No doubt the idea is vaster than the word, as the soul is wider than the body. Every idea has its breadth, length, height, and depth. Therefore, as a world is hidden in a planet, so a world of idea is hidden in a word. Think, therefore, how interesting life must become for the one who can see behind every word that is spoken to him its length, breadth, height and depth. He is an engineer of the human mind. He then does not know only what is spoken to him, but he knows what is meant by it. By knowing words you do not know the language. What you know is the outside language; the inner language is known by knowing the language of ideas. So the language of ideas cannot be heard by the ears alone, the hearing of the heart must be open for it. The seer must understand from a word spoken to him what even the one who speaks does not know, for every human being thinks, speaks, and acts mechanically, subject to the condition of his body, mind and situation in life.
