It happened that one Zen master was passing through a street. A man came running and hit him hard. The master fell down. Then he got up and started to walk in the same direction in which he was going before, not even looking back. A disciple was with the master. He was simply shocked. He said, “Who is this man? What is this? If one lives in such a way, then anybody can come and kill you. And you have not even looked at that person, who he is, and why he did it.”
The master said, “That is his problem, not mine.”
You can clash with an enlightened man, but that is your problem, not his. And if you are hurt in that clash, that too is your own problem. He cannot hurt you. And it is like knocking against a wall – you will be hurt, but the wall has not hurt you.
