The will and self are ultimately dynamic, they are their actions. This energy can be trained and directed, tuned like an orchestra. It is not a matter of a "rational interior" that poses a problem for a decorator, rather a feng-shui intelligence is called for that orients the "house" to the flow of life that takes place in it (I rather suspect this is turned on its head in most cases of feng-shui, i.e. Americans capitulate once again to "experts").
