Empty the cup- that's what Nan-in said. That means empty the mind. Ego is there, overflowing and when ego is overflowing nothing can be done. The whole existence is around you but nothing can be done. From nowhere can the divine penetrate you, you have created such a citadel. Empty the cup. Rather, throw the cup completely. When I say throw the cup completely I mean be so empty that you don't have even the feeling that “I am empty.”
Once it happened, a disciple came to Bodhidharma and said, “Master, you told me to be empty. Now I have become empty. Now what else do you say?”
Bodhidharma hit him hard with his staff on the head, and he said, “Go and throw this emptiness out.”
If you say “I am empty,” the “I am” is there, and the “I” cannot be empty. So emptiness cannot be claimed. No one can say, “I am empty,” just as no one can say, “I am humble.” If you say, “I am humble,” you are not. Who claims this humility? Humbleness cannot be claimed. If you are humble, you are humble, but you cannot say it. Not only can you not say it, you cannot feel that you are humble because the very feeling will give birth to the ego again. Be empty, but don't think that you are empty otherwise you have deceived yourself.
You have brought many philosophies with you. Drop them. They have not helped you at all, they have not done anything for you. It is time enough, the right time. Drop them wholesale; not in parts, not in fragments. For these few days you will be here with me just be without any thinking. I know it is difficult but still I say it is possible. And once you know the knack of it, you will laugh at the whole absurdity of the mind that you were carrying so long.
