Freeing
Shifting
Accepting
Accepting with grace and rounding
Balancing
Half Circling, Encircling, Surrounding, Nurturing
Flowing and Reflecting
Suspending

the 19 movements/kata's

Over time the regulatory conditions change, these are:

Going to a rotary trunk position form a symmetrical trunk position.
From a static to a dynamic COG (center of gravity).
large reaching movements instead of small hand movements.
Using narrower base support.
From visual control to non-visual / vestibular control.
From symmetrical to asymmetrical arm movements.
