The Devil key is all about materialism. Humans are, first and foremost, materialistic beings. We can’t help it. The material world surrounds and permeates us. It overwhelms us with its beauty, sensuality, terrors, and brutality. But we used to try much harder to reach beyond the material realms and toward the divine. From ancient times up until about the end of the 1900s we lavished most of our money, time, and skills on our sacred spaces. We built them huge. We built them to last. We built them high, so that when we raised our eyes we would be reminded of the divine. Our finest architects, artists, and craftspeople spent their lives making them truly awe-inspiring. But nowadays when we lift our eyes from the pavement searching for inspiration we see: Banks… That sometimes look suspiciously like… Temples and Cathedrals.
