These designs are mandalas.
Mandala means center, circumference or sacred circle in Sanskrit.
Swiss psychiatrist Carl Jung regarded mandalas as images of the soul, the center of the total personality. He suggested that mandalas reflect the natural urge to live out our potential, to fulfill the pattern of our whole personality. As with most mandalas, these are circular, symmetrical and abstract. The circle symbolizes totality of self and life. Symmetry reminds us that when change occurs in part of our soul, all of our life is affected.
