Well known as a leading teacher and author of modern spirituality and meditation, William’s inspiration comes from decades of training in esoteric philosophy and energy work. His approach is influenced by the traditions of Alice Bailey, Theosophy, Western Mysteries, esoteric Christianity, Sufism, Kabbalah, Rosicrucian, Masonic and Pagan teachings. At the same time he has a doctorate in political psychology from the London School of Economics and is an advocate of emotional literacy, so his metaphysics is grounded in everyday realities.

He is founder of the Spiritual Companions Trust and Fellow of the Findhorn Foundation. He has authored over twenty books including the bestselling Psychic Protection, The Power of Modern Spirituality, Working with Angels and The Sacred Magician. His background also includes a two-year retreat living off-grid in the High Atlas Mountains of southern Morocco.
