When it comes to peace, people say, "Just sit down and think beautiful thoughts. That's all you need." What if you are hungry and go to a restaurant and order food, and the waiter says, "You don't need to actually eat anything. Just think of the most exquisite dishes you'd like, and your hunger will go away"? No, we have to be practical. We need to feel peace every single day. And if we want to feel peace, we can turn within.
