This CD set was authored by L. Kaminoff, an experienced yoga practitioner with a special interest in anatomy. Mindful breathing is so wonderful, and these CD's may help. The outline in the Product Description seems reasonably accurate, so I won't repeat it.
Here's what I thought worthwhile:
1. Personally, I thought the author had a positive, crisp, and clearly enunciated voice tone, without a perpetually upbeat (but often artificial) "rah-rah-rah" style, or a cloyingly unnatural droning voice I've often encountered on such audios. I've fallen asleep in many lectures but not for these CD's! Other reviewers felt he was boring, but I felt his matter-of-fact style maintained my interest -- if you like this type of presentation, "Freeing" may be the one for you. Otherwise, consider something else -- no problem. It may be good for Amazon to offer segments of such CD's for you to preview, as they do with books.
2. I found his descriptions and definitions accurate without being overdetailed or overdeveloped. He made his point, he illustrated it well -- and then he moved on. Good.
3. His analogies were clear and interesting; for instance, he compares breathing to the processes found in an individual cell, which was far easier to understand than the very complicated and unfamiliar yogic system of pranas and the like.
4. The presentation seemed to "flow" well, with excellent transitions and connections with other lecture segments. I never felt the "huh?" sensation, in other words.
5. Breathing exercises formed much of the CD. They seemed excellent, and allowed me to attend to my body as it interacted with the breath, with interest and connection. I paused the CD now and then to extend the exercises.
6. He concludes with suggestions for using breath analysis in daily life (including knowing your "baseline" breathing in yoga or meditation, and observing the changes as you come under daily stress or happiness).
On the other hand, the CD has no written outlines, references, etc. -- not even how to access his website. I had to stop the CD and write down info at several points. This lack is why I gave it just four stars. A website with some diagrams, summaries, etc. would be valuable, and you may be interested in two websites associated with the author, which you can find by keying in his name to your search engine (they couldn't transfer to this review). You can find the author's DVD and book on Amazon. The author discusses anatomy frequently, and since anatomy is an important health subject, consider a reference book (such as F. Netter, Parker and Winston, the Anatomy Coloring Book, or the book on Yoga Anatomy).
