"The Complete Works of Zhu Zi·Guan Xin Shuo": "You may ask the Buddha whether this is true because of the observation of the mind. He said: The reason why a person's mind is the master of the body is that it is one and not two. It is the master and not the guest. It is the one who orders things but not the things. Therefore, observing things with the heart can understand the principles of things. Today There are things that can be reflected back on. The heart is outside of this heart. There is a mind that can control it. This heart is also called the heart.
Intention: "The Avatamsaka Sutra": "The mind is like a skilled painter, able to paint all the world. The five aggregates are all clustered together, and there is nothing you can do but create."
