When we start to suffer, it tells us something very valuable. It means that we are not seeing the truth, and we are not relating from the truth. It's a beautiful pointer. It never fails.
Reality is always true to itself. When you're in harmony with it, you experience bliss. As soon as you are not in harmony with it, you experience pain. This is the law of the universe; it is the way things are. Nobody gets out of this law.
