Aikido practice has as its main goal the achievement of one’s own harmony through a combination of movements.
There are two basic forms of movement: Irimi, “entering” and Sabaki “turning”. Irimi is the act of going forward in a straight line. Sabaki is based on the principle of rotation and it is a pivoting movement that changes the trajectory of the attack.
The celestial bodies in our galaxy are in perpetual motion. They rotate around their own axis and around other bodies. In fact, the universe is constantly rotating. Aikido follows that Universal Design.
