Symbol representing the material realm (horizontal beam) and the spiritual realm (vertical beam). Where the two beams cross represents Man - a correlation of the two - sometimes represented by a Rose.
"If it is held . . . as a cross, it will remain as one . . . with individuals where there is in their experience crosses to bear, hardships or surroundings that to them are overpowering, overwhelming, by slights, slurs, and fancies of the inactivity of a coordinating force. If these are held continually as crosses, or as things to be overcome, then they will remain as crosses. But if they are to be met with the spirit of truth and right in their own selves, they should create joy; for that is what will be built." Cayce (552-2)
