Anyone who has the habit of speaking before God's majesty as if he were speaking to a slave, careless about how he is speaking, and saying whatever comes into his head and whatever he's learned from saying prayers at other times, in my opinion is not praying. Please, God, may no Christian pray in this way.
Teresa of AvilaLearn to self-conquest, persevere thus for a time, and you will perceive very clearly the advantage which you gain from it. As soon you apply yourself to orison, you will at once feel your senses gather themselves together: they seem like bees which return to the hive and there shut themselves up to work at the making of honey. At the first call of the will, they come back more and more quickly. At last, after countless exercises, of this kind, God disposes them to a state of utter rest and of perfect contemplation.
Teresa of Avila
