The author discusses the Tausug concept of “parrang sabbil”, a form of altruistic suicide that has its origin in the holy war between Christians & Islamics in the Philippines during the 19th century. Called “juramentado” by the Spanish, it was a form of suicide in which an Islamic man went to a Christian settlement & ritually murdered non-Moslems until he in turn was killed. Complex preparatory rituals & after death rituals are described. (NBB)
