The term "monadic expression" refers to the expression of monadic consciousness in physical matter. You, the person reading this page, are one of the monadic expressions of your monadic spark (sometimes known as your "higher self" in OWS systems).
It is important to note that monadic expression is not confined to the human body. In this universe alone there are billions of different physical vehicles, and millions of different planets, from microscopic through macroscopic, suitable for the expression of monadic consciousness. It is also important to understand that the human form in no way represents any kind of "pinnacle." The human form is simply one among many.
