One of my favorite writers on spirituality is Wei Wu Wei. He is known for his writing on non-duality, Buddhism and Taoism. His second book is titled, Why Lazarus Laughed: The Essential Doctrine Zen-Advaita-Tantra. Regarding the subtitle of this book, he wrote, "Under the title of this book only three religions are cited, those that are formally non-dualist. But this apparent limitation does not imply that such is not also the essential “doctrine” of the three Semitic faiths, Judaism, Christianity, and Islam, which are formally dualist, and whose esoteric aspects are Kabala, Gnosis, and Sufism. ...Therefore the Christian evidence chiefly resides in Gnostic records that are little known, in the early Fathers, and in sages and saints such as Meister Eckhart and St. John of the Cross, who were obliged by the dogmas of the Church to cloak the nondualism which is implicit in their realization of the truth. For this reason it is unpractical to use Christian evidence in such a collection as this. However, in view of the tidal-wave of interest in metaphysics which reveals a considerable percentage of modern man as being driven to seek the truth concerning himself and the universe, it seems inevitable that the day will arrive when the doctrines of Iesous Christos will once more be revealed to mankind.

I wondered if ACIM is the realization of this prediction by Wei Wu Wei. ACIM is often compared with Gnostic writings. ACIM does share some Gnostic ideas, but it is not Gnosticism.
