Dana Marie Bell said this quote

You are the sum total of what you have seen and learned, but underneath that is a core being, a usually untouchable being, that makes you who you truly are. It can make a person into a great peacemaker like Ghandi, or a serial killer like Ted Bundy, but it is immutable. That core holds both our deepest darkness and our greatest light. It’s the harmonies layered on top of that core melody that make us who we are from day to day.
