Analysis of A Fallen Star

I thought, once, when I walked at night
 beneath the shadows of moonlight mocked,
When the air stood still and the cold mist
 of my breath built clouds that fell into nothingness
 invisible,
When the forest as a tall, hushed fortress stood
And watched with me, with skyward eyes,
And saw the far-flung, cold diamond dancing
 of flames, of stars in the infinite heavens . . .

I thought, once, I glimpsed a fleeting light
Far-off, through the boughs of the tree-sentinels
 that saw me safe along an unseen road,
a shimmering spark in the dark of night
that beckoned me, that called me thence.

Had one star fallen for me alone?

Or had I seen
 the flames of your eyes calling me from far home?
One star had fallen there -
 for love, for love,
 it had been you.
