Mandalas, a kind of yantra, are patterns with concentric rings that come out from the center and contain symbols, figures, or forces of nature (like deities, waterfalls, or
dolphins) that reveal mysteries of the universe. Psychoanalyst Carl Jung is credit with introducing mandalas in the West, using them as a therapy technique and map of the
psyche to "uncover the mystery of the unconscious and the soul."

California artist, Paul Heussennstamm, a master of painting mandalas, often depicts patterns that evoke tantric sex imagery in the union of god and goddess surrounded
in exquisite nature. Heussennstamm makes custom mandalas and teaches classes on how to make this art, in California and on journeys to countries like India and
Nepal. "You don't have to think of yourself as an artist," he says, "just close your eyes and notice the lights and colors that appear in the visual field. People draw what
their mind has conjured up, and it gives you clues as to what's really in your soul."
