Ask yourselves if you are in such a state that you would never change your heart, however difficult things may get. You must get that far. It is the summit. When you scale Satan’s ramparts and enter the spirit world, God’s existence will be proven. If you do not accomplish it, it will be like crossing the drawbridge of a castle but not entering its palace. Until the moment you gain entry, you will not be able to know anything. However much you may gaze at that castle, you cannot get in. (224-108, 1991.11.23.)
However difficult things may get, if we are not in such a state that we would never change our heart, we can always shake our mind. In other words, we must meet God across the walls of the Satan world. So what is the wall of Satan and how can we meet God across this wall? Satan's wall is a evil mind wrapping our spirit self. This evil mind is not a substance, it is like a shadow, caused by the fall of man. For example, desire for power, greed of money, greed of honor, mainly in clothing and Food and shelter. How then can we see God across this evil wall? It's too easy. It is to make full use of the original mind. That is to live as it is. Our original mind will never move with our self-interest as a center. Essentially we are always for the opponent, trying to please the other. So those who live to please our opponents are the ones who live in our original minds, and when this is done, the evil mind will disappear without a trace. As the sun floats the darkness will disappear and the evil mind will disappear without a trace. If this is possible, God is already in that person's original mind.
