Having good, pure thoughts pop into your head spontaneously or deliberately is not evil. I never meant that. God forbid if anyone thought I did. No, I mean that these ideas, though wholly commendable, will get in the way of your praying contemplatively. They hurt more than they help during this work. When you are seeking God, you won’t rest until you rest in him; the imperfect meditation on one of his saints or angels will not satisfy.
