John Kells introduced a great exercise to help us work on yielding and making a hole for the incoming energy.
We had to stand in a bow and arrow stance with one arm held up in ward off and a pole resting gently on it which was held by another person.
That person would then slowly advance the pole towards your centre. In response we had to yield to the advancing pole and create space without forcing the pole away.
This is easier said than done as the natural inclination is to force the pole aside. This was a great training exercise to work on the attributes of yielding, acceptance,no force and creating a hole.
