In this whole world everyone searches for happiness outside, but nobody understands their true self inside. Everybody says, “I” — “I want this, I am like that…” But nobody understands this “I.” Before you were born, where did your I come from? When you die, where will your I go? If you sincerely ask, “what am I?” sooner or later you will run into a wall where all thinking is cut off. We call this “don’t know.” Zen is keeping this “Don’t Know” mind always and everywhere.
