We left off yesterday, this is from the book "Instant Zen" translated by Thomas Clary. We left off yesterday where the saying when when knowledge and principle merge, environment and mind unite. It is like when drinking water once spontaneously knows whether it is cool or warm. And said yesterday, this is sort of a hallmark of the Zen school direct experience. But then he goes on now my teacher thought it may be cool or warm, all right. But what is this business of spontaneous knowing? He wondered and questioned very deeply. He asked the lecturer about the principle of spontaneous knowing, but the lecturer couldn't answer. Instead, he said, If you want to clarify this principle, I cannot explain it. But in the south, there are adults who have found out the source of the enlightened mind. They know about this matter, you will have to journey for it. Again, the South is shorthand for talking about the Zen school. So my teacher went traveling, he went to the capital city and all around the Eastern Riverlands asking every Zen adept. Let's call a teacher, every Zen teacher he could find about this matter. And every one he asked gave him a reply. Spot, some explained some spoken aphorisms. In any case, his feeling of doubt remained unbroken. So this thing about knowing yourself whether water is warm or cold and drink it really bit into him. Obviously there's so many stories of these early masters who had a similar experience with another saying another occurrence that they had read about that just didn't make sense, but they knew that there was something to it
