The epithet beautiful is used by surgeons to describe operations which their patients describe as ghastly, by physicists to describe methods of measurement which leave sentimentalists cold, by lawyers to describe cases which ruin all the parties to them, and by lovers to describe the objects of their infatuation, however unattractive they may appear to the unaffected spectators.
When people see some things as beautiful, other things become ugly. When people see some things as good, other things become bad. Being and non-being create each other. Difficult and easy support each other. Long and short define each other. High and low depend on each other. Before and after follow each other. Therefore the Master acts without doing anything and teaches without saying anything. Things arise and she lets them come; things disappear and she lets them go. She has but doesn't possess, acts but doesn't expect. When her work is done, she forgets it. That is why it lasts forever.
I am of opinion that there is nothing so beautiful but that there is something still more beautiful, of which this is the mere image and expression,--a something which can neither be perceived by the eyes, the ears, nor any of the senses; we comprehend it merely in the imagination.
