Nature is us! The "Holy Book of Nature" can teach us to understand nature as an expression of ourselves and ourselves as an expression of nature. The role of humanity in creation will change. We have not yet reached the goal for which we are intended. The Sufi master Hazrat Inayat Khan placed great emphasis at the dawn of modernity on the importance of sustainability for the new era. His vision of creation, with its dynamics and our place within it, is of timeless beauty. Even today, 100 years after his time, we should continue to study nature rather than merely using it. In a world plagued by climate change, the question of humanity and nature is becoming increasingly central. Firos Holterman ten Hove, the author of "The Soul of Stones," shows how this great Sufi master experienced and understood nature: "Universal Sufism is at the heart of this.".
