669. Body Formed Gradually, Must Decompose Gradually
"Be assured that your letter was not a bother to us. Indeed, we were happy to learn that in the autumn years of your physical life your soul was illumined by the eternal light shed upon the world by Bahá'u'lláh.
"Concerning your question about cremation, the Bahá'í law stipulates burial. The instructions of Bahá'u'lláh contained in His Most Holy Book make this law clear. Shoghi Effendi, in a letter written on his behalf to an individual believer in 1955, comments that Abdu'l-Bahá '...also explained that burial is natural and should be followed.' The explanation of the Master referred to by Shoghi Effendi is found in Tablets revealed by Him. One of those was published in Star of the West, Volume XI, No. 19, page 317, from which we quote:
'Thy letter has been received. Due to scarcity of time, I write the answer briefly: The body of man, which has been formed gradually, must similarly be decomposed gradually. This is according to the real and natural order and Divine Law. If it had been better for it to be burned after death, in its very creation it would have been so planned that the body would automatically become ignited after death, be consumed and turned into ashes. But the divine order formulated by the heavenly ordinance is that after death, this body shall be transferred from one stage to another different from the preceding one, so that according to the relations which exist in the world, it may gradually combine and mix other elements, thus going through stages until it arrives in the vegetable kingdom, there turning into plants and flowers, developing into trees of the highest paradise, becoming perfumed and attaining the beauty of color.'
'Cremation suppresses it speedily from attainment to these transformations, the elements becoming so quickly decomposed that transformation to these various stages is checked.'
"When we realize that our physical bodies are composed of elements placed in the earth by their Creator, and which through the orderly processes of His Law are continually being used in the formation of beings, we can better understand the necessity for our physical bodies to be subjected to the gradual process of decomposition. As at the time of death, the real and eternal self of man, his soul, abandons its physical garment to soar in the realms of God, we may compare the body to a vehicle which has been used for the journey through earthly life and no longer needed once the destination has been reached."
