Dear Jen,
Great link on contemplation! You found a treasure, all in one reading!
As for poverty, remember that when we promise to observe the rule: poverty, chastity, and obedience - it means we do this in accord with our state in life - which is
secular. As such, we have family and personal obligations that take precedence over any desires we might have to embrace celibacy (if we are married) or true poverty (if we have the care of a family).
But what we can strive to do is practice the deeper virtue of
detachment, which embraces poverty of spirit, so highly recommended by St. Teresa. There are very many
spiritual forms of poverty that we need to embrace in order to grow in holiness.
I see puzzles in your eye.
Remember in Story of a Soul, how Therese became upset when her artist brushes were not at her disposal? (I seem to remember somebody borrowed them) She was tempted to become indignant and outright impatient. Poverty of spirit would overlook the inconvenience, as she quickly realized. How about the poverty of spirit that she practiced whenever it came time for meals? She hid her personal preference for foods so well, that nobody could determine when she did or did not like something. She offered it up, accepting whatever was served to her without complaint or showing any facial expressions.
St. Teresa of Avila had a real problem with “points of honor,” which she finally overcame by the willingness to be less acceptable to others — poverty, which freed her from attachment to honors and being well thought of.
And many other examples you may have already thought of, since you also read these books.
