[Letter from Francis of Assisi to Clare of Asissi]
A text cited by Clare in her rule, chapter 6.3-4, which deals with poverty. She explains that after she was moved by God to follow Francis, shortly after his own conversion, when Francis saw that she and her sisters had no fear of poverty or hard work, he wrote a form of life for them. Then she cites this passage.
