SUMMARYIn spite of the best efforts of some of the greatest thinkers, the mechanisms of gravity, lift, and inertia are unknown. Part 1 of this article explored the relationship of the human body to the ever-varying gravity field. Now we describe how a deeper understanding of the physics of gravity and lift may be derived from study of the ways living systems utilize these phenomena. A novel mechanism is presented for the “lift” experienced in the Rolf work. It is suggested that lift arises from the same mechanism that returns the venous blood from the trunk and lower limbs back to the heart. A counter-current energy exchange takes place between the blood descending in the aorta and the blood ascending in the vena cava. The Rolf work optimizes this energy transfer and thereby enhances the experience of lift. This is accomplished when the great vessels are brought into appropriate relationship with each other, with the vertical, and with the various fascial layers, particularly with the double spiral/oblique musculature described by Dart. The lifting phenomena are not due to an anti gravity ‘force.” Instead, a vertical or spin or “levity” field is set up between the blood spinning and spiraling down the descending aorta and the blood ascending in the vena cava. The phenomenon is related to the “core” sensation described in Rolfing, as well as “the moving Qi between the kidneys” described in the literature of Oriental Medicine. Lift arises because the properties of space are altered in a way that reduces the inertia of the blood and of the surrounding tissues. Postmodern physics, particularly the work of William Day, is leading to logical concepts of space, energy, and motion that are highly relevant to the practice of bodywork, movement therapies, and the understanding of the phenomenon of lift.
