As far as I can understand, the author describes adequately the process one has to go through if one is ever to tap into the unconditioned dimension of the mind. The order that ensues being the outcome of a natural process, decantation, rather than an order artificially imposed by an outside agency, the conditioned mind itself.
He makes it clear through his metaphor that meditation is not an escape from oneself but just about the opposite. One must face oneself as one is, one's double talk, one's avoidance of those things that may hurt and that have been brushed under the carpet out of complacency. That this requires a sense of order and responsibility, honesty, much skill needed in observation, sustained effort.
A great master of meditation talks of meditation as the greatest of all arts. And this I understand to mean that the art of transcending one's very self ( conditioned self) is not only the most difficult by its subtlety but that it is primarily concerned with perceiving the very essence of beauty.
