While recently working a lot from the ground I have revisited the aikido notion of “extension”.
Extension for me is the sense of “bringing myself fully to the meeting”. It is both approaching and opening to my partner. It has something of Gestalt Therapy’s coming to the “contact boundary”.
Extension is what procduces the possibility of cohesiveness in the ki-musubi or the blending.
The active and receptive quality of extension transforms the contact from arbitary grabs and pressures into a unified yet morphing stream of evolving contact.
It is this that contributes my experience of the expansion time in practice. Our encounter moves from a sequence of stuttering moments into into one elongated pervasive sweep!
Strangley the sense and necessity of extension becomes for me more acute when contacting my partner from the ground.Working on the ground highlights the necessity for me to bring my whole body torso and head as well as limbs into a vital quality of extension so that that no contact is arbitary or subsiduary.
