We are responsible for what we are, and whatever we wish ourselves to be, we have the power to make ourselves.

Each man is a microcosm of the universe. Your body is made of all the elements of the world. Nature supplied all the ingredients that make your body, which means that the universe made you by donating itself. You could accurately say that you are a small walking universe that can move, whereas the cosmic universe is stationary.
