The mystic who knows the value of the word finds that word first in himself; for the secret of all knowledge that one acquires in the world, whether worldly or spiritual, is the knowledge of the self. For instance, music is played outside oneself. But where is it realized? It is realized within. A good word or a bad word is spoken from outside. But where is it realized? It is realized within. Then where is the realization of the whole manifestation, of all this creation that stands before us in all its aspects? Its realization is within.
