One of the functions of thought is to be occupied all the time with something. Most of us want to have our minds continually occupied so that we are prevented from seeing ourselves as we actually are. We are afraid to be empty. We are afraid to look at our fears.
I will not look upon the quickening sun, But straight her beauty to my sense shall run; The air shall note her soft, the fire most pure; Water suggest her clear, and the earth sure; Time shall not lose our passages.
