The central midline axis of the physical body runs through the structures of the head, spine and sacrum. Physically the spine bears weight, supports movement and houses the central nervous system. Energetically, the spine carries spiritual energy through the midline up from the legs and pelvis toward the head. In our yoga we aim to free the skeleton and the spine of its unhealthy patterns of collapse and heaviness that diminish the internal space and generate a feeling of being pulled down. An individual with a healthy spine that is able to exhibit lightness may be able to approach aging gracefully, without pain and discomfort.
