Throw the gourd into the water, push it down and it will spin

Pushing down a gourd means to do it with your hand. When a gourd is thrown into the water and pressed down, it will suddenly pop up to one side. No matter what, it is a thing that will not stop in one place.

The mind of the man who has arrived does not stop at one thing even for a bit. It is like pushing down the gourd in the water.
