Mandala is the Sanskrit word for circle.
Many cultures use the mandala in worship and meditation. In my work, I have used the mandala to aide in creative therapy to teach relaxation and the improvement of individual self performance. Making a mandala (circle) is very healing, even if it doesn't turn out perfect like these! None of mine have ever been this perfect, but I made these using a java browser. The applet is called "Kaleidoscope." If your computer is java enabled, try this link to make your own mandala!
