We have this sense that there's something bigger than us, above and beyond. If you take away the idea of God, you need to replace it with a shared moral code. Otherwise, everybody becomes very self-centred and materialistic.
I trust so much in the power of the heart and the soul; I know that the answer to what we need to do next is in our own hearts. All we have to do is listen, then take that one step further and trust what we hear. We will be taught what we need to learn.
