Here's one,

Cocoon

Sack of ashes, hanging dry
Bound with silken threads
Rasping sound of blowing sand
Heavy heart of darkened lead.
Sunken eyes are frantic now,
Gagged and tied, and tossed about
Struggles with the beast that hides.
From a stale and dismal cell
Bursting free, when time arrives
Falling light on untried wings
Glides upon the rising tide
Blinded by the fire of spring-
Lights upon a blade of grass
Tingles with the breath inside,
Lives awhile, and then it dies.
