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.
