The Merkaba literally means light spirit body as that is what the three syllables express in ancient Hebrew. To me however, the use of this symbol surfaced as a logical evolution from the sevensphere symbol I used before as the lens through which I view external reality. Does my use of a symbol originating from jewish beliefs make me a jew? No, of course not! I do not blindly ascribe to any religion, and certainly not to the horrific things that have been done under such a flag.
