Her credo is one of the clearest and most accurate operational definitions of spirituality I have ever read.
Margaret was a Dominican nun and the daughter of King Béla IV of Hungary.
She chastised herself from early childhood, wore an iron girdle, hairshirts and shoes spiked with nails.
She also performed the dirtiest tasks in the monastery.
Love only God,
Denying your own self,
Do not judge anybody.
