Learn 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 AvilaThat is how His Majesty [the Lord] rewards our good works---I mean, by predisposing us to perform better ones.
Teresa of AvilaDesire to see God, be fearful of losing Him, and find joy in everything that can lead to Him. If you act in this way, you will always live in great peace.
