This is a great question, Kate. I believe I speak to it in the Principles of Adjusting or elsewhere in this series. For now... this "sweeping" action came intuitively to me after years of adjusting. It's a massage technique I learned years ago that is said to be soothing for the recipient. For me, as we translate it to yoga, it feels as though it helps clear some of the energy that the adjustment helps liberate. Let me know if you try it... and how your students respond.
