Stillness mortifies the outward senses and resurrects the inward movements, whereas agitation does the opposite, that is, it resurrects the outward senses and deadens the inward movements.
It is a great good to give oneself up to the will of God. Then the Lord alone is in the soul. No other thought can enter in, and the soul feels God's love, even though the body be suffering.
Love of God proceeds from conversing with him; this conversation of prayer comes about through stillness, and stillness comes with the stripping away of the self.
