" But why must man suffer and sacrifice for God? At the end of his suffering and sacrifice he will find that though he began to do so for God, it has proved to be for himself. It is the foolishly selfish who is selfish, and the wisely selfish proves to be selfless. "

― Hazrat Inayat Khan , The Way of Illumination (The Sufi Teachings of Hazrat Inayat Khan Book 1)
