No-mind does not mean the unconsciousness of wood or tile. It means that when you come into contact with external objects, your mind is immovable and does not get attached to anything. There is total freedom and non-obstruction. You are not defiled by anything. On the other hand, you should not abide in non-defilement either. While you view the body and the mind as a dream and an illusion, you nevertheless do not abide in the emptiness of dreams and illusions. When you reach this state, you have then really achieved no-mind.

Please concentrate on the feeling of doubt and do not give it up whether walking, standing, sitting or lying down. This one word “Wu” is no other than the knife which can clear away this great doubt of life and death. The handle of this knife is right in your own hand. No one else can take hold of it for you, but you must do it yourself. If you are willing to lay down your life, you will be able to begin the task. However, if you are not willing to lay down your life, you should concentrate on the feeling of doubt and do not let it slip by.
