I think the terms Lesser Magic and Greater Magic can be substituted with simply "Lesser Imagination" and "Greater Imagination". Lesser Magic is using simple imaginative techniques to alter your situations, whereas Greater Magic requires a heightened awareness of ones imagination. I believe that as a Satanist, I have grown beyond what the herd mentality would call reality. I can see things commonly misplaced into the back of the ignorant mind, and I can manipulate them. This is magic.
