Many people profess a belief in the existence of a spiritual realm, often aligning with their religious training or background. (Recent surveys indicate that, on average, between 48 percent and 59 percent of Europeans claim to believe in an afterlife, while between 72 percent and 74 percent of people in the United States assert a belief in life after death.) But when confronted with the loss of a child, a spouse, or another deeply loved person, one may find that his or her belief set is deeply challenged, and some suffer a crisis of faith.
