What is true of archery and swordsmanship also applies to all the
other arts.  Thus, mastery in ink-painting is only attained when the
hand, exercising perfect control over technique, executes what
hovers before the mind's eye at the same moment when the mind begins
to form it, without there being a hair's breadth between.
	- Eugen Herrigel, *Zen and the Art of Archery*
