A recent news article in the Times of India, described Mr. Iyengar (here referred to as Guruji) and his visit and yoga demonstrations in China, where yoga is booming, in the short excerpt below:

Guruji demonstrated the subtle actions and movements of the skin, muscle and bone with the analogy of a simple leaf: the stem (centre) of the leaf is the line from the head to the feet; the veins of the leaf, which branch outwards from its stem represent the action of the muscles in the body. “Just as the veins of the leaf spread outwards, so also the skin and muscles of the legs. The entire body should not only vertically extend but also horizontally expand if one is to have a rhythmic stretch in the asana,” Guruji elaborated.
