STUDY THE FLOWER OF LIFE
This interlocking circle design is an ancient one. Called The Flower of Life it purports to be the blueprint of Creativity Itself. Look up Seed of Life. Look up Tree of Life. And draw it, trace it, color it, organize it, reorganize it, embody it. Allow your eyes to wander over it and around it until it becomes three, even four dimensional. Look at it until you see straight lines and squares and tunnels.
Be sure to breathe. ☺
