The Icosahedron shape represents movement, flow and change. It has 20 sides all of which are equilateral triangles. The Icosahedron's shape can be found in nature in the form of various viruses.
Plato assigned the Icosahedron to represent the element of water, and it is said to offer help in balancing the emotions. Working with the Icosahedron can also help facilitate a regenerating, healing energy into physical reality.
The Icoshaedron is an energy grid of the water crystal and a matrix for transmutation of both etheric and physical properties through the fluid flow of nature.
