Robert Ogilvie Crombie is probably best known as one of the seminal figures in the history of the Findhorn Foundation community in northern Scotland. He was the elderly Scottish gentleman who spoke with nature spirits. But there was much more to this man's life and work than just his association with Findhorn. As a scientist, hermetic magician, and a researcher of the psychic realms, he was in many ways a key figure in the history of esotericism in the twentieth century. His story is less-well known than it could be simply because he worked in solitude and privacy. He did not write books and did not take students or attempt to found a group or an esoteric school. When he shared some of his inner work with the world at large, he did so through the lens of the Findhorn community. In so doing, he exerted a powerful influence on the imagination and spiritual work of thousands of people around the globe, particularly in how they view humanity's relationship and responsibility to the natural world. For anyone interested in the history of Findhorn, the Western occult and magical traditions, or the life of a working adept, this book is a must-read.
