Don’t just read the book or listen to. Do what it says.
Try this for forty days.
The following quotation from A Course In Miracles is important to apply:
W-in.8. Some of the ideas the workbook presents you will find hard to believe, and others may seem to be quite startling. 2 This does not matter. 3 You are merely asked to apply the ideas as you are directed to do. 4 You are not asked to judge them at all. 5 You are asked only to use them. 6 It is their use that will give them meaning to you, and will show you that they are true.
W-in.9. Remember only this; you need not believe the ideas, you need not accept them, and you need not even welcome them. 2 Some of them you may actively resist. 3 None of this will matter, or decrease their efficacy. 4 But do not allow yourself to make exceptions in applying the ideas the workbook contains, and whatever your reactions to the ideas may be, use them. 5 Nothing more than that is required.
