classic waka stream

It is the same sky
that the two of us look on,
and yet, why is it,
this winter rain that adds to
not knowing how you may be

Meaning
We look on the same sky, and yet why does this winter rain keep adding to my not knowing how you are?
Commentary
Part Three: Agemaki

 Winter came with Niou still unable to go to Uji, and he sent this to Naka no Kimi. He puts into the winter rain his impatience at being under one sky with her and unable to meet. She answered; and at Uji, where no one came, Oigimi went on grieving over her sister's prospects.

 Kumoi is the sky where the clouds are. Obotsukanasa is the anxiety of not knowing how another fares. Shigure, the intermittent rain of early winter, is a common figure for an unsettled mind. The bond of looking at one sky and the severance made by the rain are held against each other within the poem.
