When he shall die,Take him and cut him out in little stars,And he will make the face of heaven so fineThat all the world will be in love with nightAnd pay no worship to the garish sun.

This quote is suggesting that when someone passes away, if you take their spirit or essence and turn it into a star in the night sky, their beauty will be so immense that everyone will be in love with the night sky and they will not pay attention to the bright and blinding sun.
