Getting back to the original post, I was able to download a sample of his book The Victorious Mind from Amazon for free.
I have only read a little so far. Quite frankly, I am surprised how much you can see from the sample. Anyway, as you said, it is a book about meditation and memory. The author talks about how he used memory training and meditation together to fix a very troubled mind and he says the book will share specifics so the reader can use similar techniques to help improve their own lives.
This intrigues me. In the first place, it is an application of memory techniques that you will not find in a book by Harry Lorayne. (BTW, Harry Lorayne’s books are excellent, IMO.) And I don’t remember seeing it in any other books, although I am sure I could have missed them if they exist. In the second place, I have had great success repurposing memory training as a tool to help deal with anxiety attacks that I used to experience frequently. So, his opening comments about how he made use of memory techniques in his struggle to deal with his own mental and emotional struggles seems very plausible to me.
From what I have read so far, I would say the book is offering something that I personally have not seen discussed in detail elsewhere. For that reason, I find it intriguing and am considering buying the book.
