I think joy and sweetness and affection are a spiritual path. We're here to know God, to love and serve God, and to be blown away by the beauty and miracle of nature. You just have to get rid of so much baggage to be light enough to dance, to sing, to play. You don't have time to carry grudges; you don't have time to cling to the need to be right.
Anger destroys all ability to be at peace with yourself and with others. If you harm me, it is you who lose: you lose your peace.
