The book in the series that compiles the whole concept

I found that this book is most of the series: it is that which explains the practical implementation of the principles outlined in the previous volumes.
Ultimately, I regret not having had first to have a global vision and to deepen the elements summarized in Volume 5 by means other Tomes.
Everything becomes clear and EC TOME joined my very select club of personal development books that are worth to be read / reread / owned several copies / distributed.
