"In order for a warrior to follow the path of Heiho, it is necessary to keep in mind that the essence of Heiho is to build an indomitable spirit and an iron will; to believe that you cannot fail in doing anything."
There are many paths to the truth, which can create confusion as to which is the best path. As a teacher, teach with confidence, with an indomitable spirit, and do not ask for reassurance. Be assured.
