You'll find the basic structure of Vinyasa Yoga along with some of my favorite poses and sequences in my latest article at My Yoga on Gaia!
Vinyasa Yoga arises from an intrinsic personal freedom to breathe and move in the way that is most beneficial at any given time. To call once again upon the experiential wisdom of Shiva Rea who likens this quality to a river, "there is a direction to the flow but like a river, it is allowed to find its course." In Sanskrit, this quality is called sahaja and illustrates the spontaneous response that arises within Vinyasa Yoga when we allow ourselves to be led by subtle body intuition. Whether or not the resulting movement bears any resemblance to a yoga pose.
