The world is full of suffering, it is not God's making. It is not the law of karma that makes trouble, as we have learned to know. It is not the law of cause and retribution that makes us reap what we sow. It is our own ignorance of the real world that brings us all kinds of unhappiness. We keep chasing the shadow and wanting it to be straight, to be more full, to be more beautiful, to be more proportionate, but it is only a shadow! If we get to know the real person, we care not what the shadow looks like. Similarly, if we know the real world, how beautiful, how eternal, how free it is of every disaster and suffering, we care not whether this ephemeral drama is going on, because we know this is a distorted picture being projected of the real and beautiful world. Therefore, whatever it looks like, it doesn't concern us that much.
