Time magazine has a startling article by David van Biema, "Mother Teresa's Crisis of Faith," examining a new book of her correspondence with her various spiritual directors. Apparently, unknown to anyone but these correspondents, from the beginning of her mission to tend the poor in Calcutta, she completely lost any sense of the presence of God, except for one five-week break early in this period of her life where it returned temporarily, only to disappear for good. For the rest of her life, says van Biema, she was "tormented by spiritual darkness."
That's pretty amazing. How she learned to live with this is a fascinating tale: http://tinyurl.com/23kudz
