In particular, the details and depth convered in the entirety of all Japanese books (as far as I have seen thousands of them or as have been reviewed in English) pale in comparison to the knowledge of those topics covered in my books.
Don't you think this is a bold, if not arrogant, statement? Is there not the slightest of possibilities that one of these authors, who are all stronger than you, from one of the thousands of books that you've read, has written truths in their books that you don't fully understand?
To say that the "details and depth" pale in comparison to you own self-written text seems a bit arrogant to me.
Of course, I know the reply that's coming next. Something aling the lines of go strength not equating to knowledge, how there is not evidence that their books are better, yada, yada, yada...
Surely this isn't the best way to promote the aales of your own books... I can't help but wonder what your intention is in this kind of nonsense.
