In honor of Mas Goeroe Agoeng (Grand Master) Willy Wetzel’s dream to teach and further develop the lessons and knowledge of Poekoelan, we introduce his art, Poekoelan Tjimindie Tulen.

Poekoelan is an Indonesian word, which means “series of blows with returning hands and feet”; Tjimindie means “beautiful flowing waters”; Tulen means “original”. Together, this describes the movement of this complete martial art, which flows gracefully and is effective in both combat and healing. The art is symbolized by the flexible, supple, yielding bamboo and an individualistic, beautiful rose that has thorns to protect itself. These symbols are set upon a black background, which signify the secrets and mysteries of the art.


The system’s movements are of a nature akin to water and bamboo, fluid and circular, spiraling and continuous, graceful and whip-like. Movements are derived from four animals; monkey, crane, snake and tiger. The use of these animals provide a set of dynamic dualities: soft/hard, fast/slow, small/large, fierce/playful, circular/angular and high/low. All of this is combined with a meditative, dance-like form, called the “crawl”, a movement that is completely unique to each practitioner.

Martial techniques for self-defense are joined with breath and energy for purification of the body and mind. The purpose is to waken and connect with the body, seek clarity of self, and learn to strengthen, protect and secure the human spirit core by developing calm, compassion and a high level of internal energy for use in healing. The advanced levels of training in the Tulen art inspire the student to develop not only physical skills but mental and spiritual skills as well. The three advanced phases of the Tulen System are White Dragon, Silver Dragon and Gold Dragon.

Students begin training by bowing with empty hands and open minds to our teacher. The cleansing spirit of the art pours through them, and with each step it washes and purifies them. The training drum rhythms guide the students to their own movement. To fully understand the essence of training, students are encouraged to “accept, breathe, flow and not be concerned with outcomes.” Compassion based Poekoelan offers a calm and fluidly beautiful art of self-protection and cultivation of the inner 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.
