Eyes-- The "thousand eyes" in the night that the author addresses in this poem is a metaphor referring to the dim sparkle of the stars. The one eye of the day is the sun, as the author obviously states. There is a distinct contrast between the author's use of each "eye's" brightness correlating to their respective importance. The author then relates the thousand eyes of the night to the mind. The mind has a thousand eyes because it learns many things and expresses many different things.
