The real power comes from the realisation of who you really are and always have been, it's like you finally 'remember' that this life is just one in an infinity of previous and future 'lives' and that everyone and everything is you. It's the realisation of the fact that you (and everyone else) are in fact God who came into this body to feel separated from himself, that the Universe is some kind of cosmic simulation which you've created since the beginning of time.
This realisation is what frees people from the mundane reality of existence and gives one courage to embark on the craziest of endeavours, which sometimes have the side effect of changing the entire world.
