classic waka stream

Am I, who served as
guide, the one to lose his way
coming back again,
on this road in the half dark
where my heart has not gone through

Meaning
Am I, who served as guide, the one to lose his way returning along this road in the half dark, with my heart unsatisfied?
Commentary
Part Three: Agemaki

 Kaoru brought Niou to Uji and led him to Naka no Kimi. He himself passed the night near Oigimi and got nothing. At dawn, with his mind still unsettled, he spoke this poem, and she answered. From this night the fortunes of the two sisters begin to move fast.

 Shirube is the guide, the part he had played for Niou. Kaerite is "on the contrary" with kaeru, to return, sounding through it. Kokoro mo yukanu is to be unsatisfied, and yukanu, not going, belongs with the road. A man who works for another and is left with nothing himself is set into the picture of a road in the half dark.
