After fulfilling the above requirements, imagine that the body is comprised of nothing but water molecules and that the skin is made of rubber (similar to water in a balloon). Feel the water molecules pressing against the skin as gravity begins to pull the water molecules down through the body, toward the floor. As the water molecules are pulled lower, you can feel the arms begin to swell. The fingers feel as though they are swelling to an enormous size. As gravity pulls the water molecules even lower, the thighs become thick and heavy. The water molecules flow deeper into your legs and feet until your feet feel as though they are going to burst out of your shoes. Feel the feet spread. Feel the toes spread.
Your body now feels like a pyramid, heavy at the floor and light at the top.

Continue to breath deep into the dan tian. Allow your attention to move to your feet and notice where the  primary weight is. It should be in the middle of each foot. If it's not, adjust the position of your pelvis until it is. Don't forget to be aware of the imaginary weight pulling down at your tail bone and the cord pull upward on your head.

Once you have accomplished the feeling of being grounded well to the earth or floor, imagine that the floor is pushing up against your feet, trying to up-root you. The more relaxed and grounded you become, the harder the floor pushes up against your feet.

After about 10 minutes, your feet will feel energized and your hands will become warm.
