BEFORE I begin to speak of the fourth Mansions, it is most necessary that I should do what I have already done -- namely, commend myself to the Holy Spirit, and beg Him from this point onward to speak for me, so that you may understand what I shall say about the Mansions still to be treated. For we now begin to touch the supernatural77 and this is most difficult to explain unless His Majesty takes it in hand, as He did when I described as much as I understood of the subject, about fourteen years ago.78 Although I think I have now a little more light upon these favours which the Lord grants to some souls, it is a different thing to know how to explain them. May His Majesty undertake this if there is any advantage to be gained from its being done, but not otherwise.
77 Cf. St. Teresa's definition of supernatural prayer in Relation V (Vol. I, p. 327).
78 From the outline of St. Teresa's life, Image Books Edition, (Vol. 1, pp. 27-37), it will be seen that this computation is approximately correct. The reference is to Life, Chaps. XI-XXVII.
