Whereby my Soul, as by a Mirror true,

Of her own form, may take a perfect sight.

But as the sharpest Eye discerneth nought,

Except the sunbeams in the air do shine;

So the best Soul, with her reflecting thought,

Sees not herself, without some light Divine.

O LIGHT! (which makest the Light, which makest the Day;

Which settest the Eye without, and Mind within)

Lighten my spirit, with one clear heavenly ray!
