Hello,
I have practiced martial arts in my childhood and still swith PTSD i have been prtacticed gong fu for 2 years (I abandoned because of m y new job's shedule) It is to say that this tragedy dont remove your profund tendencies and hobbies, what always you liked to. The only difference is that your energy is canalized in an other way: waiting and vigilating for an eventual enemy. That's all. It's simple but it's complicated. In my case this stragedy began at 11 year old.
Always i was an active child, loving sports and learn.
So I have readed some books of Erle Montaigue, an Australian Martial Artist (considered as first western representative of occident in China wushu competitions) His approach is very particular, it is told about reptilian brain, trauma, abise, healing with qigong and other related issues. For example, talking about a taiji technique named "P'eng" it is said that "It’s martial application is a back fist to the side of the face with a Qi draining jerking of the wrist. The corners of the eyes down to the upper cheekbone is the area that indicates childhood abuse. So this posture can be used to help with the locked up trauma cause by this condition. This area of the face also represents the heart. Look at most heart operation patients and you will see that the area of the cheeks is slightly puffy or swollen." (Interrnal Gung Fu. Vol. 2) It amazing me!
His site http://www.taiji-qigong.co.uk/Books.html the books are free to download. (amazing no!!)
The big problem is to find a good master. I hope that this can help someone!!
