One Zen monk, Bokuju, was passing through a street in a village. Somebody came and struck him with a stick. He fell down, and with him, the stick also. He got up and picked up the stick. The man who had hit him was running away. Bokuju ran after him, calling, "Wait, take your stick with you!"
He followed after him and gave him the stick. A crowd had gathered to see what was happening, and somebody asked Bokuju, "That man struck you hard, and you have not said anything!"
Bokuju is reported to have said, "A fact is a fact. He has hit, that's all. It happened that he was the hitter and I was the hit. It is just as if I am passing under a tree, or sitting under a tree, and a branch falls down. What will I do? What can I do?"
But the crowd said, "But a branch is a branch, this is a man. We cannot say anything to the branch, we cannot punish it. We cannot say to the tree that it is bad, because a tree is a tree, it has no mind."
Bokuju said, "This man to me is also just a branch. And if I cannot say anything to the tree, why should I bother to say anything to this man? It happened. I am not going to interpret what has happened. And it has already happened. Why get worried about it? It is finished, over."
This is the mind of a sage not choosing, not asking, not saying this should be and this should not be. Whatsoever happens, he accepts it in its totality. This acceptance gives him freedom, this acceptance gives him the capacity to see. These are eye diseases: shoulds, should nots, divisions, judgments, condemnations, appreciations.
