I can write the saddest poem of all tonight.

Write, for instance: "The night is full of stars,
and the stars, blue, shiver in the distance."

The night wind whirls in the sky and sings.

I can write the saddest poem of all tonight.
I loved her, and sometimes she loved me too.

On nights like this, I held her in my arms.
I kissed her so many times under the infinite sky.

She loved me, sometimes I loved her.
How could I not have loved her large, still eyes?

I can write the saddest poem of all tonight.
To think I don't have her. To feel that I've lost her.

To hear the immense night, more immense without her.
And the poem falls to the soul as dew to grass.

What does it matter that my love couldn't keep her.
The night is full of stars and she is not with me.

That's all. Far away, someone sings. Far away.
My soul is lost without her.

As if to bring her near, my eyes search for her.
My heart searches for her and she is not with me.

The same night that whitens the same trees.
We, we who were, we are the same no longer.

I no longer love her, true, but how much I loved her.
My voice searched the wind to touch her ear.

Someone else's. She will be someone else's. As she once
belonged to my kisses.
Her voice, her light body. Her infinite eyes.

I no longer love her, true, but perhaps I love her.
Love is so short and oblivion so long.

Because on nights like this I held her in my arms,
my soul is lost without her.

Although this may be the last pain she causes me,
and this may be the last poem I write for her.

Tonight I can write the saddest lines.

Write for example, 'The night is shattered
and the blue stars shiver in the distance.

The night wind revolves in the sky and sings.

Tonight I can write the saddest lines.
I loved her, and sometimes she loved me too.

Through nights like this one I held her in my arms.
I kissed her again and again under the endless sky.

She loved me, sometimes I loved her too.
How could one not have loved her great still eyes.

Tonight I can write the saddest lines.
To think that I do not have her. To feel that I have lost her.

To hear immense night, still more immense without her.
And the verse falls to the soul like dew to a pasture.

What does it matter that my love could not keep her.
The night is shattered and she is not with me.

This is all. In the distance someone is singing. In the distance.
My soul is not satisfied that it has lost her.

My sight searches for her as though to go to her.
My heart looks for her, and she is not with me.

The same night whitening the same trees.
We, of that time, are no longer the same.

I no longer love her, that's certain, but how I loved her.
My voice tried to find the wind to touch her hearing.

Another's. She will be another's. Like my kisses before.
Her voice. Her bright body. Her infinite eyes.

I no longer love her, that's certain, but maybe I love her.
Love is short, forgetting is so long.

Because through nights like this one I held her in my arms
my soul is not satisfied that it has lost her.

Though this be the last pain that she makes me suffer
and these the last verses that I write for her.

The original in Spanish

Puedo escribir los versos más tristes esta noche.

Escribir, por ejemplo: "La noche está estrellada,
y tiritan, azules, los astros, a lo lejos".

El viento de la noche gira en el cielo y canta.

Puedo escribir los versos más tristes esta noche.
Yo la quise, y a veces ella también me quiso.

En las noches como ésta la tuve entre mis brazos.
La besé tantas veces bajo el cielo infinito.

Ella me quiso, a veces yo también la quería.
Cómo no haber amado sus grandes ojos fijos.

Puedo escribir los versos más tristes esta noche.
Pensar que no la tengo. Sentir que la he perdido. Oir la noche inmensa, más inmensa sin ella.
Y el verso cae al alma como al pasto el rocío.

Qué importa que mi amor no pudiera guardarla.
La noche está estrellada y ella no está conmigo.

Eso es todo. A lo lejos alguien canta. A lo lejos.
Mi alma no se contenta con haberla perdido.

Como para acercarla mi mirada la busca.
Mi corazón la busca, y ella no está conmigo.

La misma noche que hace blanquear los mismos árboles.
Nosotros, los de entonces, ya no somos los mismos.

Ya no la quiero, es cierto, pero cuánto la quise.
Mi voz buscaba el viento para tocar su oído.

De otro. Será de otro. Como antes de mis besos.
Su voz, su cuerpo claro. Sus ojos infinitos.

Ya no la quiero, es cierto, pero tal vez la quiero.
Es tan corto el amor, y es tan largo el olvido.

Porque en noches como ésta la tuve entre mis brazos,
mi alma no se contenta con haberla perdido.

Aunque éste sea el último dolor que ella me causa,
y éstos sean los últimos versos que yo le escribo
