"Sacred geometry," a set of mathematics that focuses on the beautiful and sublime elements of mathematics as evidence of cosmic harmonies. Often discussed among hippie/New Age types.

From Wikipedia: "Sacred geometry can be described as a belief system attributing a religious or cultural value to many of the fundamental forms of space and time."
