We say that health is when the centre of gravity is in its original place; like a child’s spinning top that is perfectly balanced in motion. This situation is a state of mind, emotion and body. When the centre of gravity is properly rooted, the spirit is at ease, the vision clear; we are free and joyful. Although we often say that Sei-ki has no particular purpose, it is also true that if there is a purpose, it is to bring the centre of gravity back to its natural centre.
