How can we know that the Idea itself has any real existence apart from the Energy? Very strangely; by the fact that the Energy itself is conscious of referring all its acts to an existing and complete whole.
Quite simply, every choice of an episode, or a phrase, or a word is made to conform to a pattern of the entire book, which is revealed by that choice as already existing. This truth, which is difficult to convey in explanation, is quite clear and obvious in experience. It manifests itself plainly enough when the writer says or thinks: “That is, or is not, the right phrase”—meaning that it is a phrase which does or does not correspond to the reality of the Idea.

In ancient Roman religion, an aedicula (plural aediculae) is a small shrine.
Many aediculae were household shrines that held small altars or statues of the Lares and Penates, household gods guarding the entire house.
Other aediculae were small shrines within larger temples, usually set on a base, surmounted by a pediment and surrounded by columns. In ancient Roman architecture the aedicula has this representative function in the society. They are installed in public buildings like the triumphal arch, city gate, and thermae.
From the 4th century Christianization of the Roman Empire onwards such shrines, or the framework enclosing them, are often called by the Biblical term tabernacle, which becomes extended to any elaborated framework for a niche, window or picture.
