“This issue of nibbana: The Buddha describes it in a way that’s unclear because there’s no way you can describe it clearly. It’s like talking to a person who’s totally blind. Try describing a color in a way that’s clear. Something really yellow: Go and ask a blind person if he knows it. The more you try to describe it, the less he knows. So how do you solve the problem? You have to focus back on the cause: “Why are you blind?” You’d do better to talk about how to cure the disease in his eyes. Once his eyes are good, then you don’t have to teach him about red or green. He’ll know for himself.”
