This is again taken from Penczak's Inner Temple. An exercise to show that we can manipulate energy.
Start with hands six inches apart. Imagine lines of energy coming out of both hands to form a ball in the middle. As you breathe out imagine that you are blowing out energy exhaleing from your mouth and palms. This energy fills the ball makeing it bigger. Intend to make the ball thicker and more solid. Move the ball from hand to hand. Play with it. Stretch it. When done bring your hands together and imagine you are absorbing the energy. Then wipe your hands.
