First off, I'm far from an expert on 'sacred sex,' which is why I picked up this book. I was particularily interested in channeling sexual energy, improving multiple orgasm, and developing the ability to be multi-orgasmic (as a man).
I should also note that I'm not generally a spiritual person; I don't regularily practice anything in particular. At the same time I am interested in and familiar with activities that involve a lot of body awareness, such as yoga, pilates, dance, martial arts, meditation, etc., as well as the Hindu and Buddhist faiths.
The book highlights the Universal Tao practice of sexuality, rather than Tantric-like practices, and does a good job of briefly explaining the importance and foundations of the religion to the topic at hand. At the same time, I often found myself wondering more about the Universal Tao in general, and how sexuality fits into a more comprehensive religious tradition. I felt an incomplete picture was presented: either discuss the religious aspects fully, or leave it out entirely. As it is, I feel I would have to explore Universal Tao in order to gain full value from this work.
The chapters concerning what you'd think the book would touch on most of all, multiple orgasm, were similarily vague: what is there is thorough and informative, but details and specific guidance are lacking. Even with some experience in spiritual practices and exercises, and having developed a fair bit of body and energy awareness through other activies, I found myself barely able to experience and follow what the authors were suggesting.
The book is also widely targeted, to both naive and experienced users. However, I feel the authors managed to reach neither group fully. The instruction and guidance I bought the book for (multi-orgasmic sex practices, something probably generally practiced by highly sexually aware couples) could be sparse. The information was there and complete, but seemed to assume some previous knowledge or experience that went unacknowledged. Then, the authors would explain very simple things you'd expect highly sexual couples to know, such as the function and location of the clitoris.
Most importantly, the main thrust of the book is connecting with your partner, not being multi-orgasmic. After chapter 3, the book focuses on sharing energy, developing love, and a number of other very positive and beneficial practices that I'm glad I read about. Certainly, the authors do readers a service in not just giving them techniques without explaining their power and application. At the same time, this broad overview on connection comes at the price of specifics, leaving the promise of the title unfulfilled.
On the whole, this is a decent work. It'll open your eyes to some new sexuality concepts, and I'm sure that with practice one would develop a fuller, more spiritual sexuality. At the same time, I wouldn't recommend this book to anyone with no experience in spiritual or body-based practices like yoga, meditation, pilates, tai chi, martial arts, etc.: one would have to develop some body awareness and control before being able to undertake some of the exercises with the minimal guidance provided.
More detail, more step-by-step, and exercises to get readers to that point would've made this an excellent resource. More information on multiple orgasm and how exactly to develop that ability to feel and channel energy are, to my mind, critical. As it is, the authors are off to a good start but suplementation is necessary.
One final point: the book does include a section on intercourse and thrusting. Although this is something a lot of couples can probably innovate in on their own, it is noteworthy in that this is one of the few sexuality resources I've ever seen that touches on the actual act of intercourse and the variety of possibilities there.
