Zen meditation focus on the question, “What is the mind?”
In order to have spiritual experiences, first you need to pray. You need to focus your mind. If you can, you should descend to the zero point. What is the quickest way to achieve this? To go to the zero point, the quickest way is to humble yourself. That is why people who practice Zen meditation focus on the question, “What is the mind?” The answer is very simple. As God is the eternal, ideal subject of goodness, the mind can at any time achieve the position of an unchanging object partner in front of that subject being.
