Is anything true in this external world?

What we can do with life is what is real about it. Otherwise it's like the tree falling in the forest; it doesn't matter. Is it the history of the Bible that is important or the stories you can learn from it that can change your life. Is it that your friend has a body, is a body, or is actually ghost in disguise that is important, or is it that you act from the purity of your heart to help him?
