Spiritual Maxims, Page 36

The holiest, most ordinary, and most necessary practice of the spiritual life is that of the presence of God. It is to take delight in and become accustomed to His divine company, speaking humbly and conversing lovingly with Him all the time, at every moment, without rule or measure, especially in times of temptation, suffering, aridity, weariness, even infidelity and sin. We must continually apply ourselves, so that all our actions, without exception, become a kind of brief conversation with God, not in a contrived manner, but coming from the purity and simplicity of our hearts.
