This is another of the books which one would put in the 'law of attraction' category. Much of the book deals with techniques to make one's life better by using the inherent creative power of the mind. Koran makes some good points about visualisation and other techniques which have gained a lot of attention since Rhonda Byrne's 'The Secret', and I had to google to find out just how recent an author he is/ was. I was very surprised to find that Koran is of the early 1900's (he died in 1972); the style of the book seemed far more contemporary, to me.
While I liked the book, there weren't many 'new' points which would make me go back and read this over and over again. For someone who hasn't read any books in the 'law of attraction/ self development' category, though, this would be a good starting book.
