Fr. Timothy Gallagher discusses the Third Rule:
"Of Spiritual Consolation: I call it consolation when some interior movement in the soul is caused, through which the soul comes to be inflamed with love of its Creator and Lord; and when it can, in consequence, love no created thing on the face of the earth in itself, but in the Creator of them all.
Likewise, when it sheds tears that move to love of its Lord, whether out of sorrow for one's sins, or for the Passion of Christ our Lord, or because of other things directly connected with His service and praise.
Finally, I call consolation every increase of hope, faith and charity, and all interior joy which calls and attracts to heavenly things and to the salvation of one's soul, quieting it and giving it peace in its Creator and Lord."
