The Aikidoist develops a relaxed posture in which the weight of the body is directed towards its physiologic center in the lower abdomen. Gravity is no longer a force to be overcome. Rather it serves to support and stabilize posture. As a result, ordinary movement assumes an appearance of grace and economy.
The effects of centering are mental as well as physical. In addition vitality increases, the senses are sharpened, and one is less affected by the irritations and annoyances of daily living. This state is referred to in Japan as having hara, or strong ki. It is a manifestation of the inner quality which aids the student of Aikido to develop to his or her fullest potential in every area of life.
