The dharma can be taught. You can speak the words and learn about it, but the only real value it has in our lives is if we have some experience of it. Otherwise, it's just one more competing theory that exists in this world and there are enough competing theories already. We really don't need another one. So Zen always brings you back to your experience. I can tell you something, anybody can tell you something, but that's not the truth. You have to find it for yourself.
