Some more info
Yang ywang mings book has a formula for the iron crotch. His explaination of the testicle massage and swinging is inadequate. But he has the formula Mantak chia’s healing tao is devoid of.
The formula is supposed to be used as a pre training ‘pickle’ of the gnads. I suppose it can replace the massaging. The swinging isnt nessessary i’m told for the iron vest III techniques chia teaches.
The marrow nei kung book disclaims learning from the book even though I know several that have done it. Its mostly just a disclaimer but the seminars and video’s go into some more detail. Like how to treat the silk cloth. Do’s and donts
like training while mad/upset.
There are also other issues like humidity. Climate control is important or you get slippage. The placement of the knot is important. The HT swinging also suggests not going past a certain degree of swinging and they only swing for a short period.
The yang book doesnt say anything about it. Some are concerened about this kind of training because many hard chi kung can interfere with sexual function/feeling.
If it dulls pain, it dulls pleasure. Basic axiom. A important part of non-swinging nei kung is the tapping and massage.
Beginners should swing with the weight of the pipe and bolt first. The HT group sell a rubber coated pipe/bolt rig on the homepage. They suggest a rubber coated pipe for some reason. The basic rig is a pipe drilled and a bolt with a nut that holds the weight.
The weight is a plate with a hole, just like the ones at gyms. You place the pipe through the hole, tie on the rope and secure the silk rig.
Anyone that does this should have internal medication and over the counter meds on hand for safety. The internal pills you buy at chines shops, the yunnan biao. Dit da jow, and some muscle oil, and the zheng gu shui, both water and oil based, ect.
As one guy suggested, If you pop or bust something, take the pill and lie down. Calling 911 is going to be a big time drag. It will cost you a lot of money and try explaining to a doctor or psychiatrist what your doing and why.
Dont put the oils on before training. Only for emergency. Keep things dry. You have to clip your hairs. Well, you dont have to. Its just a good idea. (Explain that to the guys at the gym)
The ultimate goal is to bring the nutts into the body. But short term, it increases hormone production to aid the training of the marrow. What you get is yours to keep. I’m told you should be able to feel the yellow marrow sizzling out.
Definitly keep some herbs and formula’s on hand with methods like this. I’d also like to add, for excess fire conditions. Use lots of butter. In india they use clairified butter. I’m into shortbread. I have mongol blood so i’m heavly into lots of dairy products.
Milk, buttermilk, that fake chocolate milk made from whey (whey is more of a drying, air clearing substance… something you have to feel to understand). Yogurt. Mung beans and mulberrys are fire clearers. DONT BURN YOURSELF UP.
Waters okay. Drinks lots of it. But i’ve developed diabetes (bronze) and I can drink a half gallon in about 3 minutes. A double gulp at 7-11 is a ‘taste’ for me now. Your body will cook that off in no time. DONT BURN YOURSELF UP.
I dryed my lymphatic system up the other day testing out the new outdoor pools heater. Big mistake, my body wasnt even producing enough saliva for me to chew crackers.
Be real cognizant of what your thyroid is telling you. That guy looks a little light in the heel’s if you get what I mean.
