A
sacred geometry is a feature of most
folk mathematics, many forms of
theology, and of some theories of
philosophy of mathematics.
Typically, such a geometry is deemed to be beyond any algebraic description, and perhaps beyond human comprehension.
Geometry as understood in mathematics and as symbolically represented in
algebra are thought to be a projection or approximation of the sacred.
Plato's "ideal forms" were one example of this conception.
Other examples of sacred geometry include the Kabbalic Tree of Life, the Buddhist Mandala and the Chinese Feng Shui.
