To respond to open book! That is fine to talk to brothers and sisters of the love of the art. When you are looking to discuss techniques and systems. It is then you request through your hiarchy or teacher, may it be Sifu, Sensei, Professor, Master. That is why we have a ranking system. You should show respect, then respect will be given. Like we say in Hawaiian to be Ha'a Ha'a (Humble). You would reap greatness and friendship, this what we mean through protocal. Especially if he is trying to learn more about his generation from Go shin jutsu through Ken-Ju-Bo-Ai through CHA-3 Again that is through his teacher Professor Richard Lewis. Without that structure, would be all chaos! Tradition and Respect is all what was mentioned. Again to reach out to a brother or sister of the Arts that is fine. But, to discuss it! Always PROTOCAL! The old proverb- Like an open book! Loose lips sink ships. We do not want (BACHI), bad karma. With Respect and with ALOHA- A is for Akahai- to be kind and respectable, L- is for Lokahi to be humble and giving from ones self, O- is for 'Olu'Olu- to be kind and thoughtful, H- Ha'a Ha'a- to be humble and giving without any expectations, A- Ahonui- To serve & giving from ones heart. So I say to you ALOHA!
Mahalo Nui Loa! Kaleimoku with RESPECT.
