The complete poem is as follows:

My soul on your lips.

For my beloved.

When of our love, the flame of passion,
you contemplate extinguished in your breast,
because for you alone I hold my life dear,
I shall take my life on the day I lose you.

Because my thoughts are full of the tenderness
with which you enslaved me in that happy hour,
far from your gaze, they are as sad as a child,
that sleeps while dreaming of your murmuring voice.

To envelop you in kisses, I long to be the wind.
And I wish to be all which your hand touches.
To be your smile, even be your very breath,
all just to be closer to your lips.

Your words sustain me, and I wait forever,
To call you mine as one who awaits a treasure.
Far from you I comprehend just how much I love you,
and kissing your letters, I truly pine for you.

Forgive me if I lack the words with which
to tell you the burning passion that devours me.
To express my love, all which remains
is to tear open my bosom, beloved, and in your silky hands
place that beating heart which adores you.

Medardo Ángel Silva.

The original form in Spanish is as follows:

Mi Alma en tu Labios.

Para mi amada.

Cuando de nuestro amor, la llama apasionada,
dentro tu pecho amante contemples extinguida,
que solo por ti la vida me es amada,
el día en que me faltes me arrancaré la vida.

Porque mi pensamiento, lleno de este cariño,
que en una hora feliz me hiciera esclavo tuyo,
lejos de tus pupilas es triste como un niño,
que se duerme soñando en tu acento de arrullo.

Para envolverte en besos, quisiera ser el viento,
y quisiera ser todo lo que tu mano toca.
Ser tu sonrisa, ser hasta tu mismo aliento,
para poder estar mas cerca de tu boca.

Vivo de tus palabras y eternamente espero
llamarte mía, como quien espera un tesoro;
lejos de ti comprendo, lo mucho que te quiero,
y besando tus cartas, ingenuamente te lloro,

Perdona si no tengo palabras con que pueda
decirte la inefable pasión que me devora.
Para expresar mi amor solamente me queda
rasgarme el pecho, amada, y en tus manos de seda
dejar mi palpitante, corazón que te adora.
