When I have a toothache, I discover that not having a toothache is a wonderful thing. That is peace. I had to have a toothache in order to be enlightened, to know that not having one is wonderful. My non-toothache is peace, is joy. But when I do not have a toothache, I do not seem to be happy. Therefore, I look deeply in the present moment and see that I have a non-toothache, that can make me very happy already.
