"If you have a will, you don't listen with the ears but listen with the heart. If you don't listen with the heart, you listen with the breath. Listening stops at the ears, and the heart stops at the talisman. The Qi also needs to be empty. The only thing is the Tao. The emptiness is the heart. The ultimate goal of "Xinzhai" is to be one with the Tao, that is, "the Tao becomes one." The cultivation process of "Xin Zhai" is an introspection process that progresses from the outside to the inside. It is a process of "suffering from the Tao". A single-minded mind ("if one mind") is an important foundation of "Xin Zhai". Outside, we must put down our attachment to external objects. Internally, we must wash away the knowledge and desires in our hearts so that our hearts will not be blinded by greed or misled by wisdom.

"The limbs are dropped, the intelligence is deposed, and the mind is separated from the body, which is the same as the great wisdom. This is called sitting and forgetfulness." "Sitting and forgetting" is a process of self-purification from the outside in. "Falling the limbs" and "leaving the body" means forgetting the body. It is to eliminate the endless desires caused by the outward pursuit of the eyes, ears, nose, tongue, and body, to get rid of all the burdens brought about by satisfying desires, and to concentrate. Gather Qi, reflect internally, and achieve transcendence of the body.

The cultivation process of "Sitting and forgetting" and "Xinzhai" are both a process of "suffering from the sun for the Tao". Their main connotations are emptiness, tranquility, emptiness and clarity, and their ultimate goals are to become one with the Tao. . No matter what "art" or "skill" you are engaged in, you must be single-minded, eliminate all external interference, concentrate and meditate, eliminate all internal distractions, and cultivate the spirit of emptiness and tranquility until your mind is empty and clear, and you can wait and see. Only objects can be consistent with "Tao" and reach the state of "transformation".
