I've been working with A Course in Miracles for almost 5 years and don't worry about the intellectual stuff. Trying to figure it out with your mind will get you no where. Just take a lesson a day and DO THEM.
Actually DO what they tell you to DO.
Miracles will start to happen before you even know it. You might find you don't even read the text until after you've done the lessons.
There is no right and wrong way.
The root of the word Holy is Whole and I found it very helpful to refer to the Holy Spirit in my mind at the Whole Spirit and of course I am part of the Whole Spirit as we all are and that made sense to me.
