Jackson Sensei has been give the title Renshi. The character "Ren" means
"polished, tempered" and "shi" means "person". Thus Renshi indicates a
"polished instructor" or expert. "Renshi" means teacher of teachers, one who has mastered
themself. Renshi teachers the black belts and helps them to new understandings.
Renshi is the one that helps Dans find more of their own unique abilities and guides
them to see the art growing in themeselves and who builds the bridges to the future
students who are not yet born (kyu rank students). The title of Renshi is not testable,
it is earned through age and experience; it is more than just a requirements outline on
a piece of paper. Even though Jackson Sensei has the title of Renshi, he is still referred
to as Sensei.
