Tree climbing and throwing stars aside, ninjutsu encompasses principles of psychological self-defense that even the military use. Such valuable skills are readily available to you, too. Start changing your design for living right here!
Centuries ago, the art of ninjutsu was born into a world enveloped in war. That one fact makes it vastly different from styles like aikido and Brazilian jiu-jitsu, which were founded during peacetime. Because of its violent childhood, ninjutsu matured into a system that focused on fighting methods that worked on the battlefield, behind enemy lines and against multiple attackers. The art grew to encompass principles for psychological self-defense that enabled its adherents to live out their lives on their own terms, free from fear. Those same principles are now used by military personnel around the world — even though they probably don't know where the teachings came from. Because we all face adversity — granted, it may not be as severe as that experienced by a black-clad warrior 500 years ago or an Army Ranger today — ninja wisdom is just as valuable in the 21st century as it ever was.
