Means to acquire the presence of God:
It would be appropriate for beginners to formulate a few words interiorly, such as: My God, I am completely yours, or God of love, I love you with all my heart, or Lord, fashion me according to your heart, or any other words love spontaneously produces.
But they must take care that their minds do not wander or return to creatures. The mind must be kept fixed on God alone, so that seeing itself so moved and led by the will, it will be obliged to remain with God.

I love Brother Lawrence. His ‘Practising the Presence of God’ was one of the first Catholic books I read.
