"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. Painting then becomes spontaneous calligraphy. Here again the painter's structions might be: Spend ten years observing bamboos, become a bamboo yourself, then forget everything and - paint."
Eugen Herrigel,
Zen in the Art of Archery
