You do not know how you translate these symbols upon this page into thoughts, and then store them, or make them your own. Since the mechanisms of normal speech are so little known to you on a conscious level, then it is not surprising that you are equally unaware of more complicated tasks that you also perform -- such as the constant creation of your physical environment as a method of communication and expression.
It is only from this viewpoint that the true nature of physical matter can be understood. It is only by comprehending the nature of this constant translation of thoughts and desires -- not into words now, but into physical objects -- that you can realize your true independence from circumstance, time, and environment.
Your entire physical environment comes as naturally out of your inner mind as words come out of your mouths, and that man forms physical objects as unselfconsciously and as automatically as he forms his own breath.
