Container-Content

(His) mind had reached the calm of water which receives and reflects images without absorbing them; it contained nothing but itself. (Henry Brook Adams)

I knew a woman, lovely in her bones, when small birds sighed, she would sigh back at them; Ah, when she moved, she moved more ways than one: The shapes a bright container can contain. (Roethke)

The cistern contains: the fountain overflows. (Blake)
