"...and in turn the heart, your faithful echo, instructs our other faculties. In this mortal and spiritual compound, this sphere that you look upon as your kingdom, it is the heart that reins supreme under your direction. Since it has no other instincts than those inspired by you, everything that you propose delights it. What human beings and the devil would like to substitute, only disgusts and horrifies the heart...."
Jean-Pierre de Caussade
