Jujutsu Ryuko no Maki (柔術龍虎之卷)
Excerpt from the Jujutsu Ryuko no Maki 柔術龍虎之卷 (Scroll of the Dragon and Tiger)
"Be able to judge the force of an enemy’s attack and use it against them before it takes effect. Do not use your own power to handle a situation. Give up self-power, throw away your own power. In a confrontation be able to bring an opponent off balance. If possible, evade an attack. Know how to attack without necessarily being able to reach the weak points. Know how to topple an opponent by making use of leverage. Know how to immobilize an opponent with grappling, strangling or striking. Know how to strike the vital points of the body in such a way as to produce loss of consciousness, varying degrees of injury and even death. Also, one must be proficient in how to heal with the art of vital points. When confronted by the enemy and a feeling rises up in yourself that this is the enemy; it means that your heart is moving. This is already a type of loss for you. You must capture the spirit of: Hontai 本躰, Fudoshin 不動心, and Fudochi 不動智 to secure a complete win and true victory."
Section explaining the secret of Wajutsu 和術 (The Art of Accord/Harmony):
“If the enemy turns upon us we meet them; if they leave we let them leave. Facing the enemy we accord with them! Five and five are ten, two and eight are ten, and nine and one are ten. Always a nine but never a ten! All this shows is accord.”
