Life magazine has a beautiful gallery of photographs of Vodou rituals in process from Haiti . . . see http://www.life.com/gallery/62471/inside-haitian-vodou for the gallery. Warning, some of the images will seem a bit extreme to some folks (animal sacrifice and the like).
Regular readers here know I have an intense interest in ritual trance within religious practice from a variety of cultural contexts and that I am particularly intrigued by eXperiential Trance Dance and the like and have taught courses on the subject in the past (and will do so again).
Thanks to the Huffington Post for the headsup.
