Wouldn't the heart of Budo lie in the concept of the Bu, the Martial values, while everything around serve as a way to achieve a Feudal-Militaristic unit?
Example, the Torite as a tool for the warrior to execute his/her authority as Law-Keeper/soldier, while the spiritual teaching to help preserve a caste-like hierarchy within the unit, and/or help condition oneself for better performance on the battlefield.
