Mysticism is the art of union with Reality.
God is acting on your soul all the time, whether you have spiritual sensations or not.
It looks impossible until you do it, and then you find it is possible.
When you put aside your preconceived ideas, your self-centered scale of values, and let intuition have its way with you, you open up by this act new levels of the world. Such an opening-up is the most practical of all activities.
Try to arrange things so that you can have a reasonable bit of quiet every day.
Christian history looks glorious in retrospect; but it is made up of constant hard choices and unattractive tasks, accepted under the pressure of the Will of God.
