She’s awesome! But always make sure to read the commentaries on her work and spirituality to make sure that you’re getting what the Church wants you to get. Sometimes people pull things out of it that is not quite it . . . as I would tell young people, close, but not quite.
Fire Within by Fr. Tom Dubay is a good book to have.
Also, good works to have are the stories of men and women who have taken what the msytics taught and have lived it in their daily lives. Then you can get a visual. That’s why I always recommend Mother Teresa after reading Way of Perfection. She’s the poster child for that book.
Another is The Practice of The Presence of God by Brother Lawrence of the Resurrection, OCD.
