" The Third Method of Prayer is that with each breath in or out, one has to pray mentally, saying one word of the Our Father, or of another prayer which is being recited: so that only one word be said between one breath and another, and while the time from one breath to another lasts, let attention be given chiefly to the meaning of such word, or to the person to whom he recites it, or to his own baseness, or to the difference from such great height to his own so great lowness. "
