In times of natural disasters, or the man-made tragedies of war, the newspapers and television fill up with tales of human suffering. And these explanations are of use up to a point - of course we want to know how to build buildings that are better able to withstand earthquakes and so forth. Wittgenstein once said that in giving an explanation, the hardest thing is to know when to stop. At some point, all we can say is this is how it is.
Life is like that.
A large part of what this practice is about is nothing but allowing explanations to come to an end and to simply experience our life as it is. If you go back and read the stories about some of the old Zen Teachers in the koan collections, they sometimes would use some pretty drastic methods do get a student to stop thinking and simply be. But before he could even finish his sentence, Obaku hit him with his stick and threw him out of the daisan room. Three times this happened, Rinzai goes in to ask a question, and each time Obaku hits him. Finally, Rinzai gives up and goes to another teacher, and tells him the story.
