Theologically and psychologically, ACIM is elaborate for proponents of nondual spirituality in that it posits a creationist theology that regularly sounds it appears that evidently dualistic or, at fine, "certified non-dualist," what India's philosophic/theological lifestyle would call "visishtadvaita." For instance, ACIM's teachings presume the lifestyles of real souls awesome from God called "sons of God." There is a feel of "oneness" within the ACIM coaching that we are all of the Christ, the Son of God. But this "Son of God" repute is distinct from the reputation of God the Father-Mother. In other phrases, the soul is created and is cut loose the Divine Spirit.
This isn't the pure clean Advaita nondual spirituality of the ancient Indian Upanishads, the Brahma Sutras, the Bhagavad Gita, the lessons of Sankara, Utpaladeva and the Kashmir Saivas, Jnaneshvar and the Marathi Varkaris, et al., which all hold that there's most effective God, the One Divine I Am Self gambling as all selves, the One Divine Spirit gambling as all souls. Parallels to this genuinely sublime nondual spirituality of India also can be discovered in the perspectives of Mahayana Buddhism (Avatamsaka school, Tathagatagarbha college, Chan/Zen/Son Buddhism, and many others.); the lessons of the loftiest Christian mystical theologians inclusive of John Scottus Eriugena, Meister Eckhart, St. John of the Cross (see my webpages on each of them on the Religion / Spirituality section); the most illustrious Sufi masters from Bayazid Bistami and Rabi'a of Basra down through Mansur al-Hallaj, Hakim Sanai, Fariduddin Attar, Jalaluddin Rumi, Ahmad al-Alawi, Sai Baba of Shirdi, Meher Baba, et alia; and Jewish Kabbalah and Hasidic masters like Moshe Cordovero, Schneur Zalman and Menachem Mendel Schneersohn. (Again, see my webpages on several of these figures.)
All of those amazing non secular masters shared the natural nondual coaching that at the start, essentially and ultimately there may be "Only the Divine Reality," the all-superb ONE who miraculously can seem to occur on an empirical, experiential stage as the many souls or viewpoints or personal consciousnesses. But those non-public consciousnesses or souls do now not have their very own independent existence.
This is important because a dualistic theology (which is there in ACIM below its purported "nondualism") ultimately leads many parents to experience like they may be separate from their personal Source, extra like a mere puppet fixed to "someone else's" strings-- in preference to being the open, free, good sized, empty-complete Divine Self of all selves, the Pure Awareness or Absolute Reality in which all extraordinary beings "live, flow and have their being." Check out a course in miracles.
It's a fundamental trouble right here of Who/What am I, truly? Am I, in my inner most nature, simply a "creature," a "created soul," separate from a awesome Creator? Or, as the towering German Catholic mystic Meister Eckhart stated so brilliantly a few 700 years ago when he mentioned our actual identity in the back of the creaturely-issue as the "uncreated component of the soul” (i.E., natural Divine Spirit, beyond all identifications with soul or ego), am I no longer virtually this easy, open, Pure Awareness? This is the Hosting capacity for all "guests," all exceptional objects, including the notional intellectual item of a separate "God."
