Interesting suggesiton - she does have some characteristics in common with the holy women of the Orthodox tradition - a lay person who lived a type of mystic life, and a person set apart from ordinary standards (thus, a "holy fool").
Some aspects of her life remind me of another mystic thinker of the 1930s and 40s - Simone Weil. Alas, they have one negative thing in common, they both seem to have a form of anorexia.
Michael O'Brien's newest book "A Cry of Stone" is about such a woman...it's really slow and sad to read, but it reminds me of some of the very holy ojibwe women that went to church with us when I lived in Minnesota...
