I think A Course in Miracles is weird, freaky, and true! It seems like after a while you just know it's true. The contrast between the Holy Spirit's thinking and the ego's thinking becomes clearer and clearer and then foggy and then clearer and then foggy...anyway, I believe that somewhere on down the line it clears all the way up, once and for all!
In the meantime, it does really start to get fun because you just know that something is happening. It can be as subtle as a sense that everything really is going to be alright or as dramatic as realizing you've switched dimensions of time. By the way, that is actually happening as you practice true forgiveness. There are lessons that you no longer need to learn, and so, it's like the Holy Spirit is erasing those parts of the tapes!
There are many welcomed experiences along the way, but they emerge within a difficult process. Becoming aware that you are the one ego appearing as many definitely isn't pretty. That's why you have to trust the Holy Spirit who is going to show you that the ego is not you.
That sounds a bit contradictory to say that you are the one ego appearing as many while saying you are not the ego, but the ego is what you have come to believe is true about yourself. Looking at what you believe is true is a necessary part of the process. Jesus says paraphrasing, illusions are protected by not looking at them and together we have the lamp that will dispel them. Thank God!
