'It is first of all necessary to purify carefully the
hidden recesses of our heart. For that which we desire to gain by bodily
purity we must possess in the depths of our conscience, where the Lord
resides as judge and superintendent of the games He carefully observes
how we run and fight. Thus those things which we are loathe to admit in
the open will not even take shape in our interior and we will not even
be soiled by any secret connivance. For although it might escape the
notice of men, it cannot lie hidden from the knowledge of Almighty God
and the holy angels, from whom no secret is hidden.'
