There is a voice in our heads, if only we could still it, telling lies continually.
Sometimes it is the voice of self-deception, making us feel more important, virtuous, beautiful, and smarter than we really are.
It can also be the nemesis of a puffed ego undermining our confidence: "Your nose really is too big. You never will do this well. People only pretend to like you."
Other times it is the black hole of the past, trying to suck you in, never to escape: "Remember how much it hurt when he/she did that? Don't forget about how you messed up. It's too late to change."
It can also be a whispering deceiver: "You are unlovable. What you did will never be forgiven. You are such a bore."
The trick is to discern between the falsehoods and a healthy dose of reality. Lies bring despair, but truth lies in peace.
