If you have no attachment for a thing you may see, it will simply
reflect in your eyes and be gone without leaving a trace on your 
mind-miror.  If you pay no particular attention to what you hear,
no sound will stay with you.  Yesterday you may have thought
this is right and that is wrong, but today you have not carried
the same mind-picture from the past to the present.  There is 
nothing to see unless you create your own mimage.  There is no
sound to hear unless you make your own record.  There is no
form of thought unlesss you build it yourself.
