To become one with the sword

Sometimes I get striked on the men when I doesn't cover it properly with my shinai. I raise my shinai to block, but my upper body bends back instead of dodge to the direction of the shinai. The bending backward creates a space open for the opponent to reach my men.

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?"
