Ninja were the Ultimate Warriors of feudal Japan. Cloaked in darkness and secrecy, the Ghost-Soldiers of the Invisible Fist struck fear into the hearts of their enemies and wreaked havoc on those who incurred their wrath. The principles of these occult methods have not changed and apply even today.
The principles and forms presented herein are intended for use by a lone individual. Some Ninjitsu ryu (schools) advocate the use of such equipment as shuriken, grapples, shaken, even poisons and firearms. These schools train to use or improvise any weapon that may further the objective of the mission. There is much to be said for this approach, even among the schools that practice invisibility such as the Black Dragon Ryu, Therefore, sections explaining the classical Ninja weapons are included.
Yet, study of this Art does not require weapons of any sort. Sensei (teacher) once said, "A naked man, alone, in an empty room, can practice Ninjitsu." One cannot move quickly and silently when encumbered by various tools. And, if captured, these devices would certainly be confiscated. What is one to do then?
Here then are the means to be invisible in the presence of the enemy, to penetrate unseen anywhere, and to pass without leaving a trace. This is the Silent Way of the Mystic-Knights, the Moonlit Path of the Shadow-Warrior, the Invisible Assassins of Feudal Japan, the NINJA.
