Aedh said perseverance and tenacity are two uniquely human traits, that these are what define us.
We were doing a push hands drill involving folding at the hips and sinking the tailbone. He commented that this was just like in the wall squat when you started to lose your balance. I told him I was no longer doing it, and he said it didn’t matter whether my back could bend or not, do it for the hip flexibility and the awareness of my tailbone.
In the drill when I was able to fold and sink, and relax my arms, he would go flying. So it is obviously worth pursuing and I will; it’s back in my minimum practice.
