I am new to the work of Craniosacral Therapy. I'm in the beginnings of a training program, doing some required reading, and this is one of the books.
Franklyn Sills is in love with what he does, there is no question about that. He writes with lucidity and sheer reverence for the forces of Life and how they unfold within is. At times his writing is quite moving and can actually take your breath away.
I believe he wrote this book with the intention to simplify and consolidate many of the concepts within Craniosacral Biodynamics and the Osteopathic work of people like Will Sutherland and Rollin Becker, and while that intention does come forth, it isn't executed all that well. This book ends up feeling much like an old textbook that needs lots of revision by someone other than the author yet with his supervision.
I say that because the concepts brought forth by Sills, some of them difficult to comprehend from the beginning, are cluttered and made more obtuse by his writing. Some of the content feels as if Sills thought of 20 different ways to say the same thing and simply listed them all sequentially. I think the book would be much shorter if those '20 ways' were simplified into one or two.
Also, much of the terminology in this field could stand to be simplified, there are too many words used for the same thing or very similar concepts, and that isn't by any means Sill's fault or doing alone, but it certainly shines through in the text, creating further confusion.
I would still suggest buying this book, as it creates a depth of discussion that few others in Craniosacral do, but I would also suggest picking up Michael Kern's 'Wisdom in the Body'. It explains the same concepts in a much simpler way, appealing more to the layman and explicating with out being obtuse or excessively flowery with language.
