In the chapter on Mechthild of Magdeburg, Flinders writes:
The forgetting of self that must take place, the emptying of all personal
desire, cannot happen all at once. We only let go by degrees -- as little, in any one round of the upward spiral, as we are absolutely sure we have to! On the path to God, light gives way to darkness, and darkness to light, at intervals. A measure of integration takes place, and we enjoy a moment of peace and joy, but the longing sets in again, and we must again exert the terrible effort.
