"It's not just a physical exercise," White says. "It's part of my spiritual preparation and how I pray." She also calls this dance form more "context-specific," as in scripture-based. Take, for instance, the Sacred Dance Guild's "Psalm 130," choreographed by White with input from her fellow dancers. In it, White--who wears street clothes to indicate her one-ness with the congregation-- dances a solo to her spoken words of the biblical text, which begins with a discussion of humankind's sins. The history of sacred dance is long and complex. While some denominations like the Puritans banned dance for fear that it promoted carnal desire, other faiths-- from the Islamic whirling dervishes to the American Shakers-- embraced dance as a way of getting in touch with the spiritual world.
