705 Highlights to A-Course-in-Miracles.pdf:

The world can teach no images of you unless you want to learn them. There 

will come a time when images have all gone by, and you will see you know 

not what you are. It is to this unsealed and open mind that truth returns, 

unhindered and unbound. Where concepts of the self have been laid by is 

truth revealed exactly as it is. When every concept has been raised to doubt 

and question, and been recognized as made on no assumptions that would 

stand the light, then is the truth left free to enter in its sanctuary, clean and 

free of guilt. There is no statement that the world is more afraid to hear than 

this: 

I do not know the thing I am,

and therefore do not know what I am doing,

where I am,or how to look upon the world or on myself.

Yet in this learning is salvation born.

And What you are will tell you of Itself.
