This point keeps re accuring in discussion . The Bujinkan is a strong martial art made strong by those that are moving forward and understand the obvious that we are not alone ..not the only martial arts out there .
The best instructors know more than just the Bujinkan and at the same time have there feet grounded well in the roots of the Bujinkan. They are willing to allow other arts in not to change our art but for the true ideals of flow . The water cannot stop . But at the same time we in this art need to look without blinders on .
Soke Hatsumi uses his sword left handed.. This is wrong by all means of the way of the sword in the eyes of the Japanese sword. Soke Hatsumi knows this and teaches this,he also ranks people by there knowledge of military movement. So why are those teaching this Bujinkan art afraid of any change. Simply said its in the instructor.
If you lift wrong you ‘ll hurt your back by breaking muscle structure . So we want to follow close to the principles of structure and movement. The same goes for instructing, follow the principles that make the movement work the way it does. Don’t preach why you wear certain clothes . A punch is a punch a sword cut is a cut ,there are better ways to fight using less force and relaxing and better ways to cut with a sword but remember that depends on the sword edge weight and who yields it .
Movement is key with structure but an instructor that has taught his knowledge to over-sized and stronger attackers and have taught much smaller to handle these over sized aggressors. This makes your teaching true ..there is change there needs to be . Teach right by principle and live . Teach by the book and you’ll only be that good
