To transform our saying prayers into a real education in prayer, they must be said in such a way that both heart and mind absorb their content. So that you may achieve this I will give you three simple instructions:
First, do not start praying without at least some brief preparation;
Second, do not perform your prayer carelessly; but do so with attention and feeling;
Third, do not return to your usual occupations immediately [after] you have finished praying.
