"We should, during our work and other actions, even during our reading, even spiritual reading, during outward devotions and vocal prayers, stop for an instant as often as we can, to adore God in the depths of our hearts, savor him rapidly and as it were by stealth, praise him, ask him for help, offer him our hearts and thank him. What could be more pleasing to God than for us to leave aside created things a thousand times a day, to recollect ourselves and adore him interiorly? For being with God, it is not necessary to be always at church. We may make an oratory of our heart, wherein to retire from time to time, to converse with him. Everyone is capable of such familiar conversation with God."
-Brother Lawrence of the Resurrection (17th century Carmelite friar), as quoted by Jacques Phillippe on page 99-100, "section 1. Outside the time of prayer", and Part IV "Practical Advice for Personal Prayer" of his book Thirsting for Prayer
