This paper is the result of an assignment that Dr. Rolf gave us in my beginning Practitioners class. She objected to a statement, that in a balanced body, the weight goes through the bones; and she assigned us the task of stating what is correct. I was sorely puzzled, since I agreed with this statement; and anyway, I could think in no other terms. Michael Salveson, our teacher, said to me repeatedly, “it’s like a Tensegrity structure”. I had never heard of such things until then; and when I got home, I began to study them and to build them. Gradually, the light dawned on me. Since I knew that others had a hard time understanding these fundamental points, I decided to write this paper, chiefly for beginning rolfers.I dedicate this paper, then, to Michael, my teacher.
