I'd love to imagine the look of surprise on your face when you read "clarifications" about the course; thinking it doesn't need clarifying, one could say that it could often be taught or explained. But using the word "corrections" is another matter entirely. What would you really think if I told you that you don't have the course in your hands exactly as it was dictated? Two things could be happening: one is that it's impossible, and the other is that it might be true, since the course often becomes incomprehensible and even incoherent in certain aspects.
Many people stop reading it because they feel a lot of guilt for not being able to put the text into practice, even though they can do the lessons perfectly.
Let me tell you what happened. Helen wrote it exactly as it was dictated, and her assistant transcribed it exactly as Helen gave it to her. Then ego got in the way and changed it. It became a book that exhausts you, and often, if you try to explain it, it leaves both the book's instructors and students without a solid foundation. This is due to the changes that were made to words, sentences, and phrases. If you stop to think about it, Jesus would never have wanted to dictate a book like this.
There are many words that should be capitalized but are written in lowercase. There are phrases that are impossible for us to put into practice, starting from the Principles of the Course as well as the preface.
Dwelling on the error would be a mistake, so it is being corrected. You will notice how the book changes and everything becomes more engaging. And, of course, you now have the foundation to maintain your position without having to say, "The Course says so, not me."
Jesus did not dictate the Course in chapters, nor did he give the text titles or subtitles, let alone numbers. If he had wanted to, and if that had been his will, he would have added chapters, titles, subtitles, and numbers, but he didn't. Some people did. And, obviously, they did it wrong.
Good advice is not to give advice, but I dare to give you one. Read the text without considering anything that man added. And if you can, go to the corrections, and you will find the genuine book just as Jesus dictated it.
It shouldn't surprise you, since they did the same with the Bible. Everything is changed according to personal interests. The Bible cannot be corrected; you will have noticed that there are many versions, and the messages differ greatly from some to others. And in some, they don't differ so much.
ACIM can be clarified and corrected. I invite you to discover this and feel the relief of not having guilt for not being able to do something that Jesus asks of you—something that he doesn't really ask of you. You were led to believe, as usual, that he was asking something impossible. That's not the case. Jesus knows very well what you are capable of and what you will be capable of. He leads you by the hand. Without demands or guilt, but with will and joy. Which is why he dictated it. Only for your happiness.
