Pushing a student should be akin to pushing a heavy curtain.
The palm is absorbed and the fabric gives as the force moves the curtain.
The curtain does not anticipate the push.
It is moved by the push, riding the wave of force: connected, sensitive and sticky.
Yielding to a push trains the student not to resist force.
This becomes more relevant when somebody punches you.
If your body does not move when struck, the impact will shock your body and the kinetic energy will channel inside you.
