Thanks for the link to my blog! I posted a slightly more idiomatic translation in comments; here it is. Incidentally the title of the song is 'Abre la ventana' ('Open the window'), not 'Maria'.



Open the window, Maria
Let the light shine in
To every corner of your house

Look around, Maria
Our life wasn't made to be eaten away
By shadows and sadness

You can see now, Maria,
There's more to finding happiness
Than just living, growing, loving
The worst times have gone
Now your eyes are filling with light
And your hands with honey

Maria…
Your laughter breaks as the day breaks over the garden
