Duty and Loyalty
For the samurai, having done some "thing" or said some "thing." he knows he owns that "thing." He is responsible for it, and all the consequences that follow. A samurai is immensely loyal to those in his care. To those he is responsible for, he remains fiercely true.
The loyalty portion of this is very important, especially as you take on more responsibility in life. Whether you are in a leadership role on a sports team, teaching a classroom of students, managing employees, or are a caring member of a family, you should be loyal to those you are responsible for.
