I wrote this book using transcripts of my public lectures in 2016. The topics discussed at those meetings combined what I planned to tell myself and what the attendees were interested to hear about. The result was a series of lectures covering practical and theoretical aspects of spiritual search and the work on the self. The book is not a verbatim record of what I said at the talks, nor does it include most questions from the audience. I have rewritten much of the material, using my lecture notes as a basis rather than reproducing what I said initially. Therefore, although I kept the headings, the content has been altered to improve consistency and add more in-depth analysis. In any case, those inclined to learn more about self-work in general and within the Sufi context, in particular, will benefit from this book. All the more so, several aspects discussed here were never raised in my earlier books.
