In the early stages of learning the Mandala for Healing Process, participants are only allowed to use white pencil on black paper. The white represents God. The black paper is used because it best presents the contrast between color. The use of the white on black re-enforces the need for learning both discipline and techniques in this process.
"THE GREAT MYSTERY IS NOT THE APPEARANCE BUT THE TRANSPARENCY OF GOD IN THE UNIVERSE."
