The last component to know from A Course in Miracles is form and content. Form is this world and everything in it. In acim, form does not matter and is part of the “beliefs” to be turned over. However, you use everything in form, along with the judgments in your mind, as the curriculum of what to turn over for correction (forgiveness).
What does matter is content and in ACIM, content is the mind. The mind you are using for interpretation (perception) of people, places, and things, etc., counts for everything. You can only have one master: (1) the Holy Spirit Right Mind (correction); or, (2) the ego wrong mind (error) and that includes both interpretations of the ego mind.
In conclusion, consider the simplicity of ACIM which is a Course in training your mind how to perceive properly. You must return the mind to peace because the Kingdom of God is peace and you cannot see the doorway from judgment. You only see peace in peace and while sharing peace with everyone.
All ACIM says is you have the willingness to learn how to do this, study the ideas and then put it into practice. The help you need will show up; but you, my friend, must do the work of this inward journey back into the mind.
The Law of Cause and Effect is the form, or mind, you are using for interpretation will be your effect in this world. It will affect you in other ways by returning your mind back to back to peace where you eventually see the illusion of choice, because no separation occurred, and choose to give it up once and for all.
