starrycross

The explanation is:

from the combination of the four pentacles comes the central base four (pesher: 12 pointed) cardinal cross. This cross is the symbol of the Knights of Malta, who were a royal order of knights that have been been accepted into the folds of the Mother Church as an Order of Priests, but differs slightly from their form of cross, which only hints at this, "true" cross, composed of four pentagrams. The historical lesson of this is that it takes eight to constitute five. You would do VERY Well to remember this lesson as long as you continue to live.
