Through: the act of making a passage in a barrier into a through (or, in an alternate dialect of English, a door). For a door to pass to the other side of a wall, it must be entered. Until then it is a door and a passage in but not through. In the term “that is a door through the wall”, what is represented as a term indicating space is really one indicating the place where through energy has been charmed and remains available if actively entered.
