Clouds gather before rain; wait patiently and don't rush.
The image
Water over heaven: clouds rise to the sky, rain is coming. Waiting for the right time.
Judgment
需：有孚，光亨，貞吉，利涉大川。
Sincerity brings light and success. Perseverance brings good fortune; it furthers one to cross the great water. Wait patiently and you will succeed.
