Regarding the questions which you ask, concerning Bahá'í burials, etc. At the present time, the Guardian is not stressing these matters, as their establishment might divert attention from the supreme tasks we have before us. However, the answers are as follows: Under the Bahá'í teachings it seems clear that the body is not to be embalmed. The burial should take place within an hour's travel time from the place of death. The preparation for the body for burial is a careful washing, and placing in a shroud of white cloth, silk preferably. There is nothing in the teachings with regard to turning the body over to Scientific Institutions for scientific research, and therefore the individual may do as he wishes, until such a time as the Universal House of Justice may legislate on this matter, if they ever do. The practice in the Orient is to bury the person within 24 hours of the time of death, sometimes even sooner, although there is no provision in the teachings as to the time limit. (From a letter dated 2 April 1955 written to an individual believer; The Compilation of Compilations, vol. I, Baha’i Burial)
