"PREAMBLE 2 This is to ask for what I want, and here it will be to ask for mounting and intense sorrow and tears for my sins.

POINT 1 This is the record of my sins, i.e. I recall to my memory all the sins of my life, looking from year to year or from one period of time to another, and for this three things are helpful: (i) to see the place and house where I lived, (ii) the relations I have had with others, (iii) the occupation in which I have spent my life.

POINT 2 I weigh up my sins, considering the intrinsic foulness and malice of each capital sin committed, quite apart from its being forbidden."

In some ways, what I once thought of as my greatest sins, external things, don't seem like much at all.  The real sinfulness I experience is too thoroughly integrated in my being to be readily tractable.  There are some who claim that it is best, once correction has been made, to essentially destroy all memory of past ill.  Isn't it better to have it around to provide the context for understanding?
