Why take three steps back to enlarge the opening circle?
The purpose is so that every student can comfortably perform the opening and closing. This is measured from the human boundary (the skin and aura), three steps back is a distance that is not too far and not too close. If too far, we don’t feel the unity of the circle. If too close, each student is uncomfortable. The count of three is not a fixed number. The trainer may change the number to fit with the size of the room and the number of students training. As an example, a single step back is often used during belt tests with many students and limited room.
