Someone is hidden in this dark with me

I live my Advent in the womb of Mary.
And on one night when a great star swings free
from its high mooring and walks down the sky
to be the dot above the Christus i,
I shall be born of her by blessed grace.
I wait in Mary-darkness, faith's walled place,
with hope's expectance of nativity.

I knew for long she carried me and fed me,
guarded and loved me, though I could not see.
But only now, with inward jubilee,
I come upon earth's most amazing knowledge:
SOMEONE IS HIDDEN IN THIS DARK WITH ME.
