Ancestors are those who once lived in human society and, having fulfilled certain conditions, are now in the realm of the spirits. One becomes an ancestor by living and dying in a particular way. In Afrikan spirituality, to become an ancestor, one must have lived an exemplary life, shown devotion to one’s own ancestors, respected the elders,and had children. Among various ethnic groups,to become an ancestor, one must have died a good death, that is, one’s death must not have been by suicide, accident, or other forms of violence, with the possible exception of heroic deaths on the battlefield. In most societies, those dying of epilepsy, leprosy, and lunacy cannot be considered candidates for ancestor hood.
