All that is really gained in the world is in the invisible place, it looks invisible, it sounds inaudible, it cannot be touched. Unfortunately, some people have obviously got it but do not know to get it, and some people think they have received it when they have not received it. In the affairs of the world, there are parts that can be seen clearly and parts that cannot be seen clearly; there are people who can understand and there are people who cannot understand. "Those who have deep lust are shallow."
