Por ninguna ocupación dejar la oración mental, que es sustento del alma.
Don't give up your mental prayer for any other activity, for it is the sustenance of the soul.
Juan de la Cruz, Grados de Perfección, 5.
I thank God all the time that I discovered people like Francis of Assisi, John of the Cross, John Cassian, and the author of the Cloud of Unknowing. They make so much more sense to me than many of the contemporary spiritual guides I've met.
