“If you truly seek understanding, then first, empty your cup!” A common saying in Martial Arts circles . . .
It reminds me from this famous quote by Bruce Lee: “Empty your mind, be formless, shapeless – like water. Now you put water into a cup, it becomes the cup, you put water into a bottle, it becomes the bottle, you put it in a teapot, it becomes the teapot. Now water can flow or it can crash. Be water, my friend.”
