Les dejo la traduccion de la cancion al Ingles, ya que muchos que ven el video no saben español.

* A WORD:
A word says nothing
And at the same time it hides everything
Just as the wind that hides the water
Like the earth that hides the flowers

A look says nothing
And at the same time it says everything
Like the rain on your face
Or an old map; a treasure

A truth says nothing
And at the same time it hides everything
Like a bonfire that cant be extinguished
Like a stone that is born of dust.

If one day You are gone, I will be nothing
And at the same time Ill be everything
Because in your eyes there are my wings
And the shore where I drown,
Because in your eyes are my wings
And the shore where I drown.
