It disgusts us how wasteful Demons are with their finite, precious, infinitely valuable energy.

Not just the common Demon, for that we would understand. Even though they have so little they do not have the COMPREHENDING of how to truly utilize it. They dribble and drain it away in a thousand small ways. The tell-tale glow in their eyes or around their bodies of a slow leak, of energy forever lost on pointless expenditure. (We have witnessed lesser Demons use their energy to FLY instead of WALK what would have been only a few steps up!)

But even the Masters waste and spend their energy as if it is INFINTE. Every drop must be used expeditiously and to a purpose. Instead of a beam of raw power, use instead a line with which to dissect. 

Use energy to deflect energy. Use energy with the understanding that the pressure it exerts is its force divided by the area it connects with. Use the minimum amount needed to finish the JOB.

Do they not understand the difference between a Pillow and a Pin? Which would you rather lay your heads upon...
