The Source: Energy Bodies & Chakras
"Once the energy body is within a certain range, which varies for each of us individually, anyone, through discipline, can forge it into the exact replica
of their physical body&endash;that is to say, a three-dimensional, solid being. Hence the sorcerers' idea of the other or the double. By the same
token, through the same processes of discipline, anyone can forge their three-dimensional, solid physical body to be a perfect replica of their energy body;
that is to say, an ethereal change of energy invisible to the human eye, as all energy is." --Don Juan Matus
