Attitude as a ninja

After the 17th century when the world of war reigned and the world became peaceful, the mission of the ninja was away from the actual battle.
The mentality attached to the function of ninja began to take hold as a ninjutsu book.
The most extensive and varied collection of ninjutsu books is the Mankawa Jukai.

In “Mankawa Shuhai”, there is a detailed description of the mindset of Shinobi. “Right mind.
The book of shinobi is “right mindedness”. The end of persecution is conspiracy and deception. Therefore, when the mind is not in proper control, it is not able to carry out a tactical strategy.
Confucius said, “The end will not be reigned over if the book is disturbed.
The so-called righteousness lies in defending the faithfulness of the people.
If you don’t protect Ningyi’s loyalty, you can’t do something strong and brave, and you can’t be scheming in response to an accident.
If your heart is not here, you cannot see, hear, or taste it, even if you eat it.
The word here refers to Niyi loyalty.

It was said that the most important thing for a shinobi is to have a “right mind,” and without it, they are no better than thieves. You must not use ninjutsu for personal gain.
