Ironically, after years of sending medical workers to developing regions to teach that sicknesses are not caused by spirits, the western world has to admit that its own medical problems are overwhelmingly caused by spirits. It is because of their spiritual needs that Westerners engage in destructive behavior such as the use of mood-altering drinks and drugs, or overeating or oversmoking, or sexual promiscuity or perversion, or acts of violence. Call the problem low spirits, high spirits, or evil spirits. It isn’t treatable medically.
