Rewriting is about checking if each of the previous concerns is attended. By "soul" I assume you are talking about the message (both information and intention).

So rewrite is more like refactoring code: you change how it is presented not its function.

A tip would be write down your message in bullet points beforehand and, while rewriting it, check if you haven't missed a point you wanted to make.

I also believe that this acronym also establishes an order of priority for the concerns, from more important to least important: 1) Information, 2) Intention, 3) Rapport and 4) Order.

Your soul should be on the first two and they are the most important to be preserved (writing or rewriting).
