Rank in Pukulan Cimande Pusaka is valid only if it is directly certified and sanctioned by Pendekar Sanders. If you have rank in other system or it was given by someone else you are more than welcome to join the Distance Program, learn any material that you might not have been taught and then demonstrate your skills by testing to upgrade your former rank.
This means everyone is a student of Pendekar Sanders and he can talk freely to anyone, no politics and no secrecy. Students in the distance program talk directly to him via the forum.
There are no promotions for those who don’t deserve it and rank will mean something.
Guru is a "mentor, guide, wise teacher; expert in a certain area". Agung is "glorious, grand" and so in this context means that you are a teacher with distinction. You are more than just a good fighter and a good demonstrator of the art you can teach and guide others in the external and internal details of the art.
No further ranks beyond Guru Agung will be issued via the distance learning program.
