Mitsugi Saotome, a direct student of Aikido's founder, teaches the principles of Aikido through demonstration and explains the philosophy and practice of the popular martial art in his book, which emphasizes harmony and peaceful resolution of conflict. Aikido focuses not on punching or kicking opponents, but rather on using their own energy to gain control of them or to throw them away from you. It is not a static art, but places great emphasis on motion and the dynamics of movement. The elegance and precision of Saotome's technique will impress even those who have never studied martial arts. On the other hand, his clear, methadical demonstrations are worthy of study by Aikido's most advanced students as well.
