Before You Die: Attend an All-Night Trance by Rupert Isaacson

Attend an all-night trance, or healing, dance of the Kalahari Bushmen in Botswana. You join a chorus circle of women, clapping along with them as they chant to make the harmony and rhythm within which the healer dances with the spirits. When he achieves the trance, blood rushes from his nose, he screams, sings, laughs, staggers, falls in the fire. Even after rolling in the flames he is unburned. Then he puts his hands on you...
