We cannot be sure if we are loving God, although we may have good reasons for believing that we are, but we can know quite well if we are loving our neighbor. And be certain that, the farther advanced you find you are in this, the greater the love you will have for God.
Teresa of AvilaIn order to profit from this path [of prayer] and ascend to the dwelling places we desire, the important thing is not to think much but to love much; and so, do that which best stirs you to love.
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.
