poem analysis

I was wondering if I could get an analysis of the following poem:

A light seen suddenly in the storm, snow
Coming from all sides, like flakes
Of-sleep, and myself
On the road to the dark barn
Halfway there, a black dog near me

Light on the wooden rail,
Someone I knew and loved.
As we hear the dates of his marriage
And the years he moved
A wreath of dark fir and shiny laurel
Slips off the coffin

A cathedral: I see
Starving men, weakened, leaning
On their knees. But the bells ring anyway.
Sending out over the planted fields
A vegetation, sound waves with long leaves

There is a wound on the trunk,
Where the branch was torn off

A wing comes out of it,
Rising, swelling
Swirling over everything alive

thank you!
