The truth is like a piano: the notes may be high or low, one may strike a C or an E, but they are all notes. So the difference between ideas is like that between notes, and it is the same in daily life with the right and the wrong attitude. If we have the wrong attitude all things are wrong, if we have the right attitude all things are right. The man who mistrusts himself will mistrust even his best friend; the man who trusts himself will trust every one.
