The triangle represents the base number for Creation. Some common trilogies are: body, mind, and spirit; maiden, mother, and crone; father, son, and Holy Spirit; light, life, and love….
A triangle pointing upward represents the material plane rising towards spirit. The downward pointing triangle is the symbol for spirit entering matter. Intersecting them creates what is commonly referred to as a Star of David. “As above, so below,” is another way to name this six-pointed double triangle. It is by design, therefore, a perfect symbol for setting up a field to hold a creative intention that is not yet manifest in experience.
