The inner life, therefore, is seeing all things and yet not seeing them; feeling all things and not expressing them, for they cannot be fully expressed; understanding all things and not explaining. How far can such a man explain, and how much can another understand? Each according to the capacity he has, no more. The inner life is not lived by closing the eyes; one need not close one's eyes from this world in order to live it, one can just as well open them.
