White Darkness

Whether this is time or snow, passing
Through the night, earthward,
Who can tell—
Each particle only an illusion; yet massing,
Mounting over all,
Hushing the footfall,
Silencing the bell.

“I am confused,”
Said the traveler, “hearing no sound
Though my feet touch the ground
As they are used.”

Soft as a shadow on fur
The filling places
Where his footsteps were;
Lost without shape or grime
His path through the level spaces.
How can we certainly know
If this is time
Falling, or snow?
