clean energy/dirty energy

Think about the difference between clean energy and dirty energy- in human terms. When someone has a lot of emotion tied up with their energy it has a heavy feel. Think about those top athletes who just seem to be playing when they are at the top of their game, even in conversation they have a real lightness. Clean energy is like a thinner higher octane version of joy I think, I suspect it becomes awareness if there is a spectrum of such things. Or wonder.
