I am disappointed with my purchase. On the one hand because it is a question of a small part of numerology, the way of life, and secondly it brings nothing more to know that this science. It is a small book that tries to associate numerology and personal development. The author offers meditations texts that suggest positive thinking, very much in vogue. It would be interesting for the beginner but really too succins. In summary a marketing product that brings nothing more. There are other much more rewarding structures.
