This theme recurs in a hundred different ways - the inseparable polarity of opposites, or the mutuality and reciprocity of all the possible contents of consciousness. It is easy to see theoretically that all perception is of contrasts-figure and ground, light and shadow, clear and vague, firm and weak. But normal attention seems to have difficulty in taking in both at once. Both sensuously and conceptually we seem to move serially from one to the other; we do not seem to be able to attend to the figure without relative unconsciousness of the ground. But in this new world the mutuality of things is quite clear at every level. by Alan Watts
