The shape below is called the enneagram. Without the numbers it is an enneagram. With them, it has many practical, mystical, and spiritual applications.
In one of its most useful applications, the enneagram accurately reflects human personalities. There are nine types corresponding to the nine numbered points. Important relationships are modeled by the lines, and there are many interesting symmetries.

format of posts and pages
This site works best on desktop and tablet screens, where the right and left aligned images always show up correctly. If you are on a phone or other narrow-display device, I suggest turning the display so that it is wider from left to right (landscape mode) for the most readable experience. You might also find that increasing your browser’s text size is helpful. There is a lot of text in these pages.
