Renunciation has both sadness and joy in it: sadness because you realize the futility of your old ways, and joy because of the greater vision that begins to unfold when you are able to let go of them. This is no ordinary joy. It is a joy that gives birth to a new and profound strength, a confidence, an abiding inspiration that comes from the realization that you are not condemned to your habits, that you can indeed emerge from them, that you can change, and grow more and more free.
~Sogyal Rinpoche
