"Your body holds memories of pain, anger, fear. It holds them in your tissues, conditioned responses that attempt to protect you from further injuiry, like scar tissue. It warps and twists you. When you collect enough of them, they are like armor. But Jedi wear no armor. Armor both protects and numbs. Jedi must expose themselves fully to the currents of the universe.
I can teach you how to remove some of these wounds. Think of them as boulders, obstacles on the river of energy. Learn to flow around your fears and angers instead of crashing against them. Learn to do this well enough, and you can even direct the river to move the boulders for you, widening the riverbed, increasing the flow of energy. The point, the value is not in the exercises, or not exclusively there. The greatest value is in transitioning between one excersize and the next. All life is movement between states, between moments. Evolve into your excellence."
