Gora pathe expands on that teaching in four chapters, which we shall see. But before entering into the essence of the teaching, a note of caution: often people are uneasy about it. Often people get shaken up about it. There is a mature way of understanding this teaching, and there is an immature way of Understanding this teahing. And believe me, i've come across people who have misunderstood this, and it can be dangerous. It's like a knife. If you don't handle it well, you can cut yourself.
