Mandalas are traditionally used in many eastern spiritual traditions as a tool to aid meditation. In western culture, mental health counselors often use mandalas as a form of stress relief, a tool for art therapy, and as a meditative exercise. We have used mandala printouts with therapy groups, during stress management presentations, and as a fun little handout to leave on waiting room tables.
