We couldn't see the truth because we are seeing too many things.
If you are watching television, how can you read a book?
If you are reading a newspaper, how can you drive a car?
If you are thinking violence, how can you understand a message of peace?
If your heart is filled with hatred, how can you understand love?
If you already have fixed concepts in your mind, how can you understand the true message of a book?
Sometimes we already decided the content of a book before we open and read the first page!
