Book Three, Chapter 53
That the Grace of God is not Communicated to the Earthly-Minded

Son, My grace is precious; it does not suffer itself to be mingled with external things nor with earthly consolations.  You must, therefore, cast away every obstacle to grace, if you desire to receive its infusion.  Choose for yourself a retired place; love to dwell with yourself alone; seek not to be talking with any one, but rather pour forth devout prayer to God, that you may keep your mind in compunction, and your conscience pure.  Esteem the whole world as nothing; prefer attendance on God before all external occupations.  For you can not both attend to Me and at the same time delight yourself in transitory things.
