Master Yunmens Koan

The koan is a dialog between Zen Master Yunmen and his student, by which the master used his statement to provoke the "great doubt" and test his student's progress in Zen practice.

A student asked Master Yunmen, “When this student didn’t raise a thought, is there still a sin or not?” The Master said, “Mount Everest!” Why did he say so?

Why did he say so? If you know the answer come and check it out. Don't discuss this with others, it is neither helping you nor them. Anytime let's have tea and an interview!
