Everything you say is true.
Don't leave out one thing that's so
common its overlooked.
Breathing.
Our Aikido lives on
Kokyu.
Kokyuhou, and
Kokyuryoku.
Breath Power.
I believe that deep breathing creates a state of
heightened awareness and physical ability
.
and this
concentration is called ki.
even in English,
concentration refers to a mental process
as well as a condition of mechanical energy.
Could you agree with this explanation?
