"Soresu is the most defensive of all of the Forms, and was developed to counteract the advancing blaster technology throughout the galaxy. Most opponents that the Jedi faced during the Galactic Republic time carried blasters. Soresu utilizes motions occurring very close to the body to achieve near-total protection, efficiently expending as little energy as possible to execute these moves. This technique exposes as few target zones on the body as possible, making a well-trained practitioner nearly invincible. Practitioners of Soresu comfortably remain on the defensive until their opponents make a mistake; only then do they strike offensively. It focuses heavily on counterattack and defensive strikes - there are no preemptive strikes in the form. Soresu can best be described as a passive form and one to be used by Masters who are extremely patient. Soresu users do not wish to fight, or harm. Even during a fight they prefer to remain on the defensive, and they will strike only when absolutely necessary, or if their opponent drops his guard during battle." Yes, he is a teacher as well. Like all Jedi Masters. "The main weakness of Soresu is that it leads to very prolonged combat against skilled enemies."
