Where the goal of the cargo cult is to invoke and create, another aspect of sympathetic magic is to protect and control. In a healing rite from Jewish mysticism, a person who wanted bleeding to stop would sit under a drain, as others poured water over him, all saying a formula that predicted that as the water flow stopped, so would the blood flow cease..[more...]
