How does Henry James use imagery in The Beast in the Jungle?

Imagery:

Something or other lay in wait for him, amid the twists and the turns of the months and the years, like a crouching Beast in the Jungle. It signified little whether the crouching Beast were destined to slay him or to be slain. The definite point was the inevitable spring of the creature; and the definite lesson from that was that a man of feeling didn't cause himself to be accompanied by a lady on a tiger-hunt. Such was the image under which he had ended by figuring his life.”
