I knew that the library was also the materialization of a certain level of the psyche, even as our world is. Only there, time is laid out like space is here. The windows of the library coincide with definite places in our space-time. In our world, these points of intersection may appear as natural objects, and these correlate with coordination points in your psyche. Moving toward these coordination points in your mind automatically lines up your consciousness to some extent with this other reality, and stabilizes conditions enough to allow for more or less conscious entry and return.
