I hope you don't take this as an offensive tone, but since my youngest son was cremated in traditional Japanese fashion, I have a bit of experience with cremation. As a result of his sudden death and we were stationed in Japan, we had limited choices, short of sending the body back to either of our parents for a burial. Far from family, other than my mother's family on mainland, my wife traumatized from the loss of our first born, the decision fell on me. Wrong or right, the decision was mine. So as you can see cremation is a very culturally sensitive issue with me. In fact as Jim mentioned, my son ashes are placed in an urn and rest traditionally in a specific shrine for him, since our current location is not our families final resting place. With this said, my intention to place this PDF had more to inform those who are not sure how to properly bury a family member the necessary consideration to respectfully intern a loved one.
I've seen the posts regarding cremations. I would like you to know that the energy needed to completely cause bone to ash white has to be very high. Simply burning a funeral pyre will not get the job done. Additionally the use of wood as a fuel source will intermix with whatever body ashes are consumed from your pyre. If that is the intent of those that choose to cremate bodies, it will be a very lengthy process requiring lots of wood to cremate the remain completely. While I respect each of your inputs, please note, that even with the high LP gas used to cremate my son, part of his skull was not completely turned into ash. So from common experience and a my family's culture that relies solely to honor their dead, it is not as easy as one might think.
