One of my favorite sentences from the Lotus Sutra says, “when you have great joy you will become a Buddha” – Chapter II. I have said it before, however, I think it is worth saying again. When you have great joy, when you allow the joy of the dharma to fill your life, then you will become a Buddha. This great joy is not the complete elimination of problems, but it is the belief in the assurance of being a Buddha.
