Language forms the structure of the conditioned mind, or spirit. Language is how we were spiritually programmed, language is what we must use to reprogram ourselves. In reprogramming, we must use language in the way it is used originally. That is, we must use words in the way other people use them. We cannot use a private language, any more than we can use a screwdriver to perform the job of a wrench. Obviously a private language sets up a wall between ourselves and other people. More ominously, it sets up a wall between the conscious (using this private language) and subconscious, and thus makes it impossible to understand or reprogram the latter.
