We teach Poekoelan Tjimindie Tulen, a traditional martial art brought to this country from Indonesia in 1956. It draws on the most effective elements of Judo, Kempo, Kung Fu and Karate. Since Poekoelan is a complete martial art, it’s much more than just self-defense. Students find well being and empowerment of body, discipline of mind and strength of spirit.

Concealed Carry – No Weapons Allowed

A strange thing happened after a self-defense class for Real Estate Agents at Tulen Center this past week. When the class was over, as usually happens, participants hung out chatting. One of the women, a very professional realtor in a suit with a snazzy matching handbag, wanted to thank me and gave me her card. She said she got a lot out of the class and was very grateful. Then, as she casually patted her purse with a big smile, she told me that she also carries a gun with her at all times and has a “concealed carry” permit.

It never occurred to me that anyone would bring a gun into Tulen Center, and I was taken aback. It didn’t matter to me that she had it hidden in a purse, that the safety was on, and that no one ever saw it. I did not want that gun in our school! Period.

We have precious small people in Tulen Center. Heck, we have precious big people here too! Even the PDX FBI, with all their years of training, have had six gun accidents in their weapons room in the past 10 years. Guns discharge by mistake. Guns get into the wrong hands. Bringing a gun into our school is not OK with me, or Mas Goeroe Jeff.

We remove our shoes, drop our bags and bow onto the floor as a sign of the respect that we have for this place. We do chores, selfless service and spend time with our beloved teammates in here. We challenge one another, support one another, encourage one another when the going gets tough and we lift one another up so that we can all be our strongest and highest selves. Having a gun in our school is the antithesis of everything we do and say.

So in case we have not been clear enough, please know that weapons are NOT ALLOWED in Tulen Center. Don’t be surprised if you see a sign up to that effect!

As Mas Goeroe Jeff said with his tongue in his cheek: At Tulen Center, we use FAKE WEPONS ONLY!

This is not a missive on my opinion of guns in general, the NRA, people carrying guns and weapons, assault rifles, or anything of the sort. This is just me, telling you, in no uncertain terms, that guns and other weapons, are not allowed into our school.
