The most potent and acceptable prayer is the prayer that leaves the best effects. I don't mean it must immediately fill the soul with desire . . . The best effects are those that are followed up by actions-when the soul not only desires the honor of God, but really strives for it.
Teresa of AvilaWhen the soul, through its own fault... becomes rooted in a pool of pitch-black, evil smelling water, it produces nothing but misery and filth.
Teresa of AvilaGod gave us faculties for our use; each of them will receive its proper reward. Then do not let us try to charm them to sleep, but permit them to do their work until divinely called to something higher.
Teresa of AvilaKeep this in mind, for it is very important advice, so do not neglect it until you find you have such a fixed determination not to offend the Lord that you would rather lose a thousand lives and be persecuted by the whole world, than commit one mortal sin, and until you are most careful not to commit venial sins.
Teresa of Avila
