More recently, leaders in the Engaged Buddhism movement, including Thich Nhat Hanh, also identify a need to return to a sense of self which includes the Earth.[12] Joanna Macy describes a collective shift – referred to as the "Great Turning" – taking us into a new consciousness in which the earth is not experienced as separate.[13] Sufi teacher Llewellyn Vaughan-Lee similarly grounds his spiritual ecology work in the context of a collective evolutionary expansion towards oneness, bringing us all toward an experience of earth and humanity – all life – as interdependent. In the vision and experience of oneness, the term "spiritual ecology" becomes, itself, redundant. What is earth-sustaining is spiritual; that which is spiritual honors a sacred earth.[14][15]
