Light's Interrupted Amplitude

All summer connotations fill this light,
a symmetry of different scales—the site
of fibrous silence, the velvet lace
of iris, alders the moon can ignite.
One feels the amplitude of grief, the pace
of oscillating stars, power in place
where time has crossed and left a breathy stain.
A body needs the weight and thrust of grace.
I want to parse the logic, spin and domain,
the structure mourning will allow, the grain
of certainty in two estates, the dance
of perfect order, flowing toward its plane.
That bird you see has caught a proper stance, 
unfaithful to its measure, a pert mischance
of divination on the move, the trace
of sacred darkness true to light's advance.
