If we start worrying whether our nose is too big or too small, we should think, “What if I had no head? - now that would be a problem!” As long as we have life, we should rejoice. If everything doesn't go exactly as we'd like, we can accept it. If we contemplate impermanence deeply, patience and compassion will arise. We will hold less to the apparent truth of our experience, and the mind will become more flexible. Realizing that one day this body will be buried or burned, we will rejoice in every moment we have rather than make ourselves or others unhappy.
