Power corrupts because it is so difficult to obtain. When someone has struggled to gain power and finally succeeds, they often spend the rest of their time trying to hold on to it. What can get lost in the shuffle is the reason for seeking power. Ironically, power as a means to its own end is impotent on a personal level because it is based on external control.
Empowerment, on the other hand, is not for its own sake, maintains its strength from inside itself and is obtainable by everyone. The ability to be, without struggle, without context, is to be empowered. Then you can do anything.
