"As often as you can during the day, recall your mind to the presence of God…. Consider what God is doing, what you are doing. You will always find God’s eyes fixed on you in unchangeable love. Our hearts should each day seek a resting-place on Calvary or near our Lord, in order to retire there to rest from worldly cares and to find strength against temptation. Remember frequently to retire into the solitude of your heart, even while you are externally occupied in business or society. This mental solitude need not be hindered even though many people may be around you, for they surround your body not your heart, which should remain alone in the presence of God. As David said, “My eyes are ever looking at the Lord.” We are rarely so taken up in our exchanges with others as to be unable from time to time to move our hearts into solitude with God." - Saint Francis de Sales

INTRODUCTION TO A DEVOUT LIFE
Treatise on the Love of God
Prayer of Saint Francis de Sales
Lord, I am yours,
and I must belong to no one but you.
My soul is yours,
and must live only by you.
My will is yours,
and must love only for you.
I must love you as my first cause,
since I am from you.
I must love you as my end and rest,
since I am for you.
I must love you more than my own being,
since my being subsists by you.
I must love you more than myself,
since I am all yours and all in you.
from Treatise on the Love of God by Saint Francis de Sales
