The courtyard where the sentinels stand.

Passage

Now let us return to our beautiful and charming castle and discover how to enter it. This appears incongruous: if this castle is the soul, clearly no one can have to enter it, for it is the person himself: one might as well tell someone to go into a room he is already in! There are, however, very different ways of being in this castle; many souls live in the courtyard of the building where the sentinels stand, neither caring to enter farther, nor to know who dwells in that most delightful place, what is in it and what rooms it contains.
