2.5 is the best I could give this book.
While reading it, I noticed many things and unfortunately, most disappointed me and few were perceived positively.
First of all, I will say that this book -being 750 pages long- definitely has something to offer to the reader. It is labeled as mysticism but I would say that it is a blend of mysticism, science and self-help. Zeland draws from many philosophies -eastern and western- to craft his theory of Transurfing.
Some techniques and mostly, specific mindsets and attitudes can be very practical and useful. These principles, if applied correctly, can reduce one's stress levels, anxiety, fear and uncertainty about generally planning and executing things in life. Guided by these instructions, the conscious reader who will try to apply them, can create a sense of control over his/her life. So there is a potential for improvement and the author heavily emphasizes on the practical side of utilizing knowledge to improve one's life.
Additionally, Zeland provides many examples to make his points clear and elaborates on concepts enough to clarify them as needed. Another useful and very helpful feature is the inclusion of a summary in the end of each chapter. In this way, the author helps the comprehension and retention of the content, as this is what summaries do, and by making these summaries, he automatically communicates which ideas are significant (as they're mentioned in the summary) and which are not (as they are not mentioned). These summaries are necessary as many chapters expand over 10 or more pages and there are many ideas mentioned in them.
To end with the positives, I will say that Zeland has also done a good job at maintaining a balance between the theoretical and the practical element. In the book, theory is generally followed by practical applications and instructions to facilitate them and I believe most readers will appreciate this, consciously or not.
However, I must say that I found so many features of the book problematic that I was just impressed. These shortcomings are just too many, even for such a 750-page book like this one.
Many typographical errors can be found in the English version and even russian letters are included at some points. The errors are not so problematic usually, but in many chapters they just appear too frequently and hence, become really distracting.
On a similar note, the English version has a big problem with punctuation. Lack of punctuation is almost present at every chapter, with commas being the main absence. This hindered my comprehension at some points.
In terms of writing, Zeland often makes leaps in his reasoning and ends up supporting irrational arguments, either generalizing too much or just coming to a senseless conclusion. At times, he makes seemingly important statements but never proceeds to explain them and just leaves them be. These features were very noticeable to me throughout the entire book.
Another problematic aspect of writing is repetition: this book could have been at least 100-150 pages shorter if it hadn't been for the awful repetitions. Repeating certain concepts and ideas to emphasize their importance or to remind them to the reader is almost always acceptable. However, this book goes too far with the amount of repetitions being uncontrollable and Zeland explaining one concept in detail for two or more times when he has, in fact, explained it earlier in the book. Naturally, this just increased the pages and at moments just left me wondering if he had agreed on a certain number of pages to fill for some reason. By constantly repeating concepts, he also distracts the reader when something new is discussed and then 3-4 pages are devoted to re-explaining something which was presented earlier.
Finally, the biggest problem of this book according to me, is that it tries to literally explain every phenomenon in this world by using a single theory - that of Transurfing. Yes, Transfuring is based on other ideologies - as mentioned above - but whoever read the book, can very easily understand what I mean. The author tries to apply his theory to explain physical and psychological phenomena that are just beyond epistemological reach. There is just no single scientific discipline that can explain every aspect of our complicated lives and that's the reason behind the necessity of having many disciplines. In the scientific world, each theory is a different toolshed that is good at explaining one or few aspects of life. Combined theories (toolsheds) aid in a better, more complete understanding of the world, so using one toolshed to explain everything is like being myopic.
Note: I found the last 10 pages of the book the most interesting, as some of Carl Jung's remarkable ideas are discussed and they happen to match well with the content of the book.
