In the Gestalt theory of perception this is known as the figure/ground relationship. This theory asserts, in brief, that no figure is ever perceived … - Alan Watts

The natural world gives us many examples of the great effectiveness of this way. The Chinese philosophy of which judo itself is an expression — Taoism — drew attention to the power of water to overcome all obstacles by its gentleness and pliability. It showed how the supple willow survives the tough pine in a snowstorm, for whereas the unyielding branches of the pine accumulate snow until they crack, the springy boughs of the willow bend under its weight, drop the snow, and jump back again. If, when swimming, you are caught in a strong current, it is fatal to resist. You must swim with it and gradually edge to the side. One who falls from a height with stiff limbs will break them, but if he relaxes like a cat he will fall safely. A building without 'give' in its structure will easily collapse in storm or earthquake, and a car without the cushioning of tires and springs will soon come apart on the road. The mind has just the same powers, for it has give and can absorb shocks like water or a cushion. But this giving way to an opposing force is not at all the same thing as running away. A body of water does not run away when you push it; it simply gives at the point of the push and encloses your hand. A shock absorber does not fall down like a bowling-pin when struck; it gives, and yet stays in the same place. To run away is the only defense of something rigid against an overwhelming force. Therefore the good shock absorber has not only 'give,' but also stability or 'weight.

Really, the fundamental, ultimate mystery — the only thing you need to know to understand the deepest metaphysical secrets — is this: that for every outside there is an inside and for every inside there is an outside, and although they are different, they go together.

Earth is in heaven. It spins, falls, and floats in a spiral nebula. Earth is not opposed to heaven: it belongs in it as a member of the whole company of the stars.
