But if the higher part of the soul is in the upper part of the head, how is it that it experiences no disturbance? That I do not know, but I do know that what I say is true. I suffer when my prayer is not accompanied by suspension of the faculties, but, when the faculties are suspended, I feel no pain until the suspension is over; it would be a terrible thing if this obstacle forced me to give up praying altogether. It is not good for us to be disturbed by our thoughts or to worry about them in the slightest; for if we do not worry and if the devil is responsible for them they will cease, and if they proceed, as they do, from the weakness which we inherit from the sin of Adam, and from many other weaknesses, let us have patience and bear everything for the love of God. Similarly we are obliged to eat and sleep, and we cannot escape from these obligations, though they are a great burden to us.
