When i too long

When I too long have looked upon your face, Wherein for me a brightness unobscured Save by the mists of brightness has its place, And terrible beauty not to be endured, I turn away reluctant from your light, And stand irresolute, a mind undone, A silly, dazzled thing deprived of sight From having looked too long upon the sun. Then is my daily life a narrow room In which a little while, uncertainly, Surrounded by impenetrable gloom, Among familiar things grown strange to me Making my way, I pause, and feel, and hark, Till I become accustomed to the dark.
