Master Black Belt
Right. My Sifu says to do so it takes practice. You must beging to Visualize your Force traveling downward. In other words in Aikido we would say make yourself heavier. But my Sifu often talks aboout finding your center of gravity and then planting yourself to floor. There is a practice. First you practice your Horse on bricks that are flat. Then you stand on the bricks slightly up the long way. Then stand on the bricks totally vertical with out them falling. When you can do this your well rooted.
My teacher was showing the difference between going low in a horse stance and actual rooting. If you can sink and relax(chen and song) you will be more stable and rooted then if you were just sitting in Ma bu or horse stance. Internalizing your stances and footwork will make them more stable.
