Peace of mind has nothing to do with the external world; it has only to do with our connection with God. Love really is the answer. We're here only to teach love. When we're doing that, our souls are singing and dancing. When we remind ourselves that we are spiritual beings, that life and love are the flame eternal, that's when our soul is nourished.
For, there is a Mystery that many call God, manifesting as Universal Love, a set of Laws and a Great Process. That Process works through each and all of us, and that Process is perfect. As we discover this fundamental truth in the journey of our loves, we find that wherever we step, the path appears beneath our feet.
