"She walks in beauty like the night"
Like the night walks. Walks right through our world. Inevitably. Invariably. Nothing is as certain as that the night will walk straight through your life. Tonight. Mysteriously. Sensuously. Like her.
"Of cloudless climes and starry skies"
When there are no clouds in the sky, you can see the stars better. I would like to fly through fields and fields of stars.
"And all that's best of dark and bright"
Her shadow that follows her, and follows you, the best of dark. If you're going to be dark, be dark like that. Lustrous. Poised, sensually, ripe and ready to drop. Oh, the shadow knows. She knows what she knows and you don't know what she knows. But you are ready to find out.
"Meet in her aspect and her eyes"
How she appears. The beauty of which you will drown in. You will forget to look for the being that sits on the throne behind her eyes. But she will remind you, penetrating you forever with her perfect gaze.
