Now let us return to our beautiful and delightful castle and see how we can enter it. I seem rather to be talking nonsense, for, if this castle is the soul, there can clearly be no question of our entering it. For we ourselves are the castle: and it would be absurd to tell someone to enter a room when he was in it already! But you must understand that there are many ways of "being" in a place. Many souls remain in the outer court of the castle, which is the place occupied by the guards; they are not interested in entering it, and have no idea what there is in that wonderful place, or who dwells in it, or even how many rooms it has. You will have read certain books on prayer which advise the soul to enter within itself: and that is exactly what this means.
