Relax your feet towards the earth; lift your head-top to the universe. Your body mass relaxes downward; your spirit of vitality goes upward.

This is much like a pebble dropping into water. (The body does not raise up during this process.)  Click on photo for demonstration – it will download then you can  open in video file.
