Human beings suffer.

They torture one another.

They get hurt and get hard.

No poem or play or song

Can fully right a wrong

Inflicted and endured.

History says, Don’t hope

On the side of the grave,’

But then, once in a lifetime 

The longed for tidal wave

Of justice can rise up

And hope and history rhyme.

So hope for a great sea- change

On the far side of revenge.

Believe that a further shoreIs 

Is reachable from here.

Believe in miracles.

And cures and healing wells.

Call miracle self-healing,

The utter self revealing

Double-take of feeling.

If there’s fire on the mountain

And lightening and storm

And a god speaks from the sky

That means someone is hearing

The outcry and the birth-cry

Of new life at its term.

It means once in a lifetime

That justice can rise up

And hope and history rhyme.

by Seamus Heaney
