Robert Browning - My Star lyrics

All, that I know Of a certain star Is, it can throw (Like the angled spar) Now a dart of red, Now a dart of blue; Till my friends have said They would fain see, too, My star that dartles the red and the blue! Then it stops like a bird; like a flower, hangs furled: They must solace themselves with the Saturn above it. What matter to me if their star is a world? Mine has opened its soul to me; therefore I love it.
