Oneness Lessons in ACIM

The purpose of this Blog is to assist you with deepening into A Course In Miracles (ACIM) by clarifying the concept of Oneness, often called non-duality.

“Complexity is not of God. How could it be, when all He knows is One? He knows of one creation, one reality, one truth and but one Son. Nothing conflicts with oneness.”


The Teachings of the Course are completely non-dual in nature. As a Life Coach that Coaches using the principles of ACIM and as an ACIM Group Facilitator for a number of years, I have noticed that the idea of Oneness remains elusive, even to veterans of the Course; that the viewpoint of Oneness is absent in most ACIM learning aids. Oneness cannot be grasped, but reaching toward it is vital for noticing where we have declared that there is “something else”.

“What is everything leaves room for nothing else. Yet is this magnitude beyond the scope of this curriculum. Nor is it necessary we dwell on anything that cannot be immediately grasped.”


Although it is not necessary, we shall find it greatly rewarding to have the patience to accustom our minds to this abstraction. For this reason, the focus of this blog will be on the concept of Oneness as expressed in the Workbook for Students.

I chose the Workbook lessons because it provides Course students with an opportunity to apply the theoretical to daily life. It is the opportunity for Course students to transform information to Knowledge. It is the task of the Holy Spirit in your mind to use the tools, (terms and concepts) that your education has provided you to provide the teaching necessary to do this. To know the Course vocabulary is to provide a powerful tool to aid this end.

The Key to A Course in Miracles

Oneness – “What is the same can not be different, and what is one can not have separate parts.”

This Course is about training the mind to accept the abstraction of Oneness. This training cannot be done effectively by telling because our mind is no longer accustomed to this abstraction.

“W-pI.169.5:1-7 Oneness is simply the idea God is. 2 And in His Being, He encompasses all things. 3 No mind holds anything but Him. 4 We say “God is,” and then we cease to speak, for in that knowledge words are meaningless. 5 There are no lips to speak them, and no part of mind sufficiently distinct to feel that it is now aware of something not itself. 6 It has united with its Source. 7 And like its Source Itself, it merely is.”


That said, the task of the Holy Spirit is to teach us Oneness because that is what we are. In this Course, Oneness is also called, God, Heaven, and Love. The form this teaching is to interpret this world in such a way that we notice the barriers we have placed in the way of experiencing our Actual Self. This noticing is the first necessary step to choosing against these barriers.

All other teachings in the Course are for the purpose of reinforcing this Oneness teaching, from the Holy Spirit:

1 The Holy Spirit serves Christ’s purpose in your mind, so that the aim of specialness can be corrected where the error lies. 2 Because His purpose still is one with Both the Father and the Son, He knows the Will of God and what you really will. 3 But this is understood by mind perceived as one, aware that it is one, and so experienced. 4 It is the Holy Spirit’s function to teach you how this oneness is experienced, what you must do that it can be experienced, and where you should go to do it.

1 All this takes note of time and place as if they were discrete, for while you think that part of you is separate, the concept of a Oneness joined as One is meaningless. 2 It is apparent that a mind so split could never be the Teacher of a Oneness which unites all things within Itself. 3 And so What is within this mind, and does unite all things together, must be its Teacher. 4 Yet must It use the language that this mind can understand, in the condition in which it thinks it is. 5 And It must use all learning to transfer illusions to the truth, taking all false ideas of what you are, and leading you beyond them to the truth that is beyond them. 6 All this can very simply be reduced to this:

7 What is the same can not be different, and what is one can not have separate parts.


For each lesson in the Workbook, I will supply a commentary highlighting the Oneness aspect of its teaching. The way that I recommend that you use this blog is:

  1. Click “LESSON ###” to read the workbook lesson
  2. Browse back to read the commentary in italics above
  3. Follow the instructions in the workbook lesson

Some commentaries are short and some are not. Occasionally, there will be brief essays (there is a poem) to assist you more broadly with the teachings of Pure Oneness in ACIM.
