Cremation is the reduction of the body into ashes and bone fragments by fire. This option is a very personal choice. There are both positive and negative views to cremation.
The positive view has the attributes of practical, cheaper, ashes, no casket, and the soul leaves the body. Whereas the attribute of soul leaves the body has a spiritual benefit which leads directly to deep religious convictions, the other attributes bring about a variety of more down to earth benefits.
