Martin Luther

There are plenty of reasons why it’s a bad idea to write a book about ascending spiritual heights. The first is because that book has been written—by Plato (Symposium), Plotinus (Enneads), Pseudo-Dionysius (Mystical Theology), Dante (Divine Comedy), Bonaventure (The Mind’s Journey into God), Thomas Aquinas (Summa Theologiae). There are many more, and they are weirder.
