By word is not meant a word which is audible only to the ears; by word is meant all that is conveyed to you, all that is expressed and comes to you as a revelation. It means that what you hear with the ears, what you smell with the nose, what you taste, what you touch, what you perceive through all the different senses and through all that becomes intelligible to you - that is a word. It is life's mission to convey something to you, and everything that it conveys to you is a word. Through whichever sense you experience it, through whichever sense it is conveyed to you, it is a word.
