Insane - Words used in A Course in Miracles

The world we see is a picture of our inner confusion and makes no sense. It is clearly understood that a loving God could not have made this, which is exactly what the insanity of it is meant to prove.

[Workbook Lesson #53.1(11)  "My meaningless thoughts are showing me a meaningless world."] 
Since the thoughts of which I am aware do not mean anything, the world that pictures them can have no meaning. What is producing this world is insane, and so is what it produces. Reality is not insane, and I have real thoughts as well as insane ones. I can therefore see a real world, if I look to my real thoughts as my guide for seeing. 

 You cannot evaluate an insane belief system from within it. Its range precludes this. You can only go beyond it, look back from a point where sanity exists and see the contrast. Only by this contrast can insanity be judged as insane.                      T-9.VII.6:1-4. 

When a brother acts insanely, he is offering you an opportunity to bless him. His need is yours. You need the blessing you can offer him. There is no way for you to have it except by giving it. This is the law of God, and it has no exceptions. What you deny you lack, not because it is lacking, but because you have denied it in another and are therefore not aware of it in yourself. Every response you make is determined by what you think you are, and what you want to be is what you think you are. What you want to be, then, must determine every response you make.                  T-7.VII.2:1-8.
