When I was teaching and leading retreats I learnt a beautiful way to pray the breath prayer or centering prayer. Using the phrase “Be still and know that I am God” start with the whole phrase, breathing in slowly and saying to yourself “Be still and know” and breathing out say to yourself “that I am God.” Then with each successive breath shorten the phrase, ending with the word “Be” (see below). And then just sit with that thought, reflecting – What does it mean to simply “Be,” in the faith that we are not alone. 
Be still and know that I am God
Be still and know that I am
Be still and know
Be still
Be
