Alice A. Bailey (1880-1949) was a prominent British-American writer, theosophist, and spiritual teacher whose work laid the foundational bedrock for the modern New Age movement. As the founder of the Lucis Trust and the Arcane School, she authored twenty-four esoteric books, the majority of which were famously dictated telepathically by a spiritual teacher known as "The Tibetan" or Master Djwhal Khul. Her comprehensive teachings on esoteric psychology, meditation, and the spiritual hierarchy remain incredibly influential in modern Western esoteric thought.
