Whether you know it or not, you are an enlightened being. We put a lot of emphasis on knowing this, because by knowing it we suffer less. When you think that you are something less than an enlightened being, you can find all kinds of things to suffer about. When you need a break from suffering, remember that you are an enlightened being. There is nothing more wonderful to be.
Enlightenment does not take into account how you look or how much you know or even how you feel. It is just what you are. Remembering that feels nice.
