My second contribution to this thread is that in my Aikido I am not interested in connecting mentally. Physical connection is is merely because our body is stable reality. All techniques and motions are based on connection from true self to other true self.
In life this reminds me to do the same and not go into mind versus mind or physical versus physical. In true self there is no versus.
That's a good way of putting it, I think, that in true self there is no body vs mind. Still, I would be interested how exactly that works in life, because in my experience, blending mind and body is a lot harder than it sounds.
