There is no mystery to the transmutation of the body of the Christ. For having attained in the physical consciousness the at-onement with the Father-Mother-God, the completeness was such that with the disintegration of the body - as indicated in the manner in which the shroud, the robe, the napkin lay - there was then the taking of the body-physical form.
This was the manner. It was not a transmutation, as of changing from one to another. Just as indicated in the manner in which the body-physical entered the Upper Room with the doors closed, not by being a part of the wood through which the body passed, but by forming from the ether waves that were within the room, because of a meeting prepared by faith. For as had been given, ‘Tarry ye in Jerusalem - in the upper chamber - until YE be endued with power from on high.’ As indicated in the spoken word to Mary in the garden, ‘Touch me not, for I have not yet ascended to my Father.’ The body (flesh) that formed that seen by the normal or carnal eye of Mary was such that it could not be handled until there had been the conscious union with the sources of all power, of all force. But afterward - when there had been the first, second, third, fourth and even the sixth meeting - He THEN said: ‘Put forth thy hand and touch the nail prints in my hands, in my feet. Thrust thy hand into my side and BELIEVE.’ This indicated the transformation.
