f the three books I recently "read" by Feldenkrais (see, however, How to Talk About Books You Haven't Read), this is the most accessibly written. It comes at a later stage in his career than the other two, I believe, when his systems of Structural Integration and Awareness Through Movement were pretty fully developed. So actual application of his ideas is presented, which is helpful to getting an idea of what he's all about.
The last 1/4 to 1/3 of the book gets into a basic Awareness Through Movement sequence. This is a good place to start to learn about the technique.
