The two eyes of the world by St. Ephrem the Syrian

“Behold the world! To it were given two eyes;
Eve was the left eye, the blind eye;
the right eye, the luminous eye, is Mary.
Because of the eye that grew dark, the whole world became dark.
Then men, groping in the shadows,
will consider every stone on which they stumble to be a god.
They have called lies the truth.
But when the world once more begins to shine, by the other eye
and the light of heaven taking up dwelling in the cavity of this eye,
then men will rediscover unity, perceiving that what they had found
was the downfall of their lives.”

Ephrem the Syrian, Hymns on the Church 37, 5-7; CSCO 199, 90.
