Half-instructed confessors have done my soul great harm; for I could not always have such learned ones as I would have desired. They certainly did not wish to deceive me, but the fact was that they knew no better. Of something which was a venial sin, they said it was no sin, and out of a very grave mortal sin they made a venial sin. This has done me such harm, that my speaking here of so great an evil, as a warning to others, will be readily understood.
Teresa of AvilaThe surest way to determine whether one possesses the love of God is to see whether he or she loves his or her neighbor. These two loves are never separated. Rest assured, the more you progress in love of neighbor the more your love of God will increase.
Teresa of AvilaThe 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 AvilaA beginner must look on himself as one setting out to make a garden for his Lord's pleasure, on most unfruitful soil which abounds in weeds. His Majesty roots up the weeds and will put in good plants instead. Let us reckon that this is already done when the soul decides to practice prayer and has begun to do so.
