Those who meditate unceasingly upon the holy and glorious name [of Jesus] in the depths of their heart can sometimes see the radiance of their own spirit-intelligence. For when the mind is profoundly concentrated on this invocation, we feel experientially how it starts burning off all the layers of dirt that normally suffocates the soul.
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.
