How to Investigate Self-Doubt

We can't undo our beliefs of separation and your bad or your better until we're with each other. One of the examples I love of this is a camp called Building Bridges, where they took teens that were from Palestine and teens from Israel and had them live together for a while. And these were young people that had a deep sense of the other as the enemy that had really in very horrific ways affected their lives. It's like, who are you really underneath that unreal other? If I don't know you, it's easy to hate you. Okay, so this is the beginning of taking this veil of beliefs. What do we do?"
