The author explains how through his medical and religious experiences he has discovered another method of healing. He believes that many supposedly "incurable" patients are the victims of ancestral control. He therefore seeks to liberate them from this control. By drawing up a family tree he can identify the ancestor who is causing his patient harm. He then cuts the bond between the ancestor and the patient by celebrating, with a clergyman, a service of Holy Communion in which he delivers the tormented ancestor to God.
