Translation
When I am crossed, I come to the narrow play. I put the hilt of my sword between your hands and I raise both arms high with my sword. I will throw my left arm over both your hands, and I will wrap both arms with your sword under my left arm. And I will not stop striking you until I am tired. The play that follows me, that the scholar does, is my play and I want to do that next.
Explanation
When the swords are crossed at the middle as the 3rd master, with both combatants having their right foot forward, you are in a momnet of equalibrium. As the 7th scholar, you take the initiative by binding your opponents arms.
Using the flat of your blade, slide your sword down the length of your opponents blade until you hit their crossbars. Using the contact point of the crossbars and the blade as a pivot point, push your hands forward. You want the crossbar of your own sword to go between your opponents hands and underneath their hilt. As you do so, you will need to step through with your back foot. This is the moment shown in the picture.
Be sure to step in as deep as you can into your opponents space. Keeping your elbows in tight, drive your arms straight up. This will lift your opponents sword and hands. With your left hand, let go of your own sword and roll your hand over both your opponents arms. This is a movement from the inside to the outside, in a similar manner to a hooking block.
This will bind your opponents arms under your left arm. Your sword will be chambered to deliver the devastating flow on techniques of the 8th and 9th scholars.
