In dealing with numbers and geometry there is a lot of symbology at every turn.

The equilateral triangle when facing upwards is the symbol of the element of Fire.

The number 3 indicates spirit or the soul (think of the trinity).

In the realm of the elements, the fire of our soul blends with the element of earth (our bodies) giving us life.

So Fire and soul can be seen amplified by the symbology in this piece. And in the Unity series this is one of the most dominant themes I strive to express is this fundamental connection we all share as souls living this human experience here together on Earth, and the ability we all have to get to know and explore this most primordial part of our being/existence.
