The ego is the worst confidence trickster we could ever imagine because you don’t see it. The problem is that the ego hides in the last place you’d ever look, within itself. it disguises its thoughts as your thoughts, its feelings as your feelings, you think it’s you . Peoples need to protect their own egos, knows no bounds. They will lie cheat, steal, kill to maintain what we call ego boundaries. People have no clue that they are in prison they don’t know that there is an ego they don’t know the distinction. At first its difficult for the mind to accept that there is something beyond itself that there is something of greater value and greater capacity for discerning truth than itself. In religion the ego manifests as the devil and of course no one realizes how smart the ego is because it created the devil so you can blame someone else. in creating this imaginary enemy it made a real enemy for ourselves and that becomes a real danger to the ego. But that is of the egos creation. There is no such thing as an external enemy no matter what that internal voice is telling you. All perception of an enemy is a projection of the ego as the enemy. In that sense you could say that 100% of external enemies are of our own creation. Your greatest enemy is your own perception, your own ignorance, your own evil.
