“If you know something simply by memorizing it, there can still be doubts. If you know the truth, that’s the end of your doubts. It’s like this water cooler that has only a single opening for the water to go out. It won’t go out any other way. If you tilt it in any other direction, the water won’t go out, for there’s no opening. And the advice you hear from this person here is for you to go right to that opening. Try to make your mind go right to that opening. If you try to pour the water out in another direction, it won’t come out, for there’s no opening.
You have to pour it in this direction, and it will flow right out. “Oh. This is how it comes out.” That’s when you understand it.”
