ST TERESA OF AVILA
(1515-1582)
No soul on this road [of prayer] is such a giant that it does not often need to become a child at the breast again. (This must never be forgotten: I may repeat it again and again, for it is of great importance.) For there is no state of prayer, however sublime, in which it is not necessary often to go back to the beginning. And self-knowledge with regard to sin is the bread which must be eaten with food of every kind, however dainty it may be, on this road of prayer: without this bread we could not eat our food at all. But bread must be taken in moderate proportions.
