Oh my friend Metis... I think we had a similar thread in the Abrahamic Religion section some months ago...
As a Baha'i we have a procedure for burial and most Baha'is know we do not cremate or have the body embalmed so this is per our laws. It is believed the body which which formerly was a place associated with the Soul should be respected:
"The spirit has no more connection with the body after it departs, but as the body was once the temple of the spirit, we Bahá'ís are taught that it must be treated with respect."
(Compilations, Lights of Guidance, p. 200)
Over the past century in my family I've noted both burial and cremation... My aunt, uncle and grandmother were cremated while my great grandparents, parents and brother were buried in marked grave sites... I have some relatives in a mausoleum. When the grave stone of my great grandfather began to show the wear and weathering of the past century I gladly had the stone refreshed and restored.
I cannot provide this service to my aunt, uncle and grandmother because their ashes were scattered and we know not where they are....
