To the extent that there are any personal matters in the book, they are designed to illustrate common mistakes. My mistakes and errors are set out in the beginning of the chapters. Then the chapter explains how to get the principle right. Other than showing how poor a student I have been, my presence in the book is entirely secondary. I do bear testimony about the truth of the teachings, which I think is required for a book of that nature. But the book is entirely about you, the reader.
I reiterate several times in the text that it is not a book for every reader. It is not publicized, advertised, or promoted in any way. It is entirely a word-of-mouth book which will find appropriate readers without any effort on my part to promote it.
