This article examines whether a group of Brazilian Kardecist-Spiritists are using the symbols of medicine and science to gain respectability and to better promote their beliefs and ritual activities or whether they are using the view of the world proposed by their founder to forge a new paradigm to replace science, as we know it. Their therapeutic practices, which range from the performance of surgeries without anesthesia and antisepsis to "teleporting" the astral bodies of patients to the spirit world where (...) they are treated for illnesses acquired during previous lifetimes are described and analyzed in terms of their worldview which postulates reincarnation. Data indicating positive results from a sample of patients treated for illnesses they claim to be caused by experiences in previous lives are presented. (shrink)
