I always said 'poetry saved my life' and what i meant was when i was at my most despondent, reading a poem that I connect with in the often mysterious ways creative arts can personally reach into us, would transform my deep disappointment (with the world or myself) into deep gratitude for that connection.
I rarely get despondent any more, but if i were to be, this new favorite book of mine would be a lifesaver, just for the beauty of the language. Every word seems necessary in the ways only words can. I highly recommend (though everyone's taste is their own) Doireann Ni Ghriofa's A GHOST IN THE THROAT.
