Review: "On average, we breathe through one nostril for about three hours until the tissue becomes slightly engorged; then we switch to the other side. The nostril we breathe through affects which brain hemisphere we use." (p25)"[T]he female brain processes both language and feeling at the same time far more efficiently than the male brain does." (p20)These two quotes should tell you what you need to know about the quality of the "science" contained in this book.Lord, if this is what we teach our teachers...

Review: I really got into belly dance workouts about 6 years ago and purchased this video at that time. I remember hating it and thinking that it was the most worthless video I'd seen. After falling off the belly dance wagon, I now lead a group of women who are learning to belly dance using instructional videos. In going through my collection I revisted this video and realised that it would have made a great introduction to the world of belly dance. I plan on teaching a new group next year and will use this video the first night for those who are interested in the history and basic moves. I am so glad that I gave this video another chance.
