The other day while practising with Chou-Sempei (周群堯), I got hit again like this. I realised that I didn't trust my shinai enough. I didn't have the confidence that it can defend me against my opponent.
But then isn't it the same with attacking? To commit the strike, throwing the body onto the opponent to execute a powerful strike, is also to trust in the weapon in your hand that it's going to slice the opponent in half.
Didn't the folk use to say: "Becoming one with the sword?"
