So, I saw that there's a lot of good stuff on this forum, and, after downloading some ebooks, I thought it would be good to retribute back somehow.
So, here is my first "donation" to TTB library of awesomeness:
http://www.highexistence.com/the-wim-hof-method-revealed-how-to-consciously-control-your-immune-system/
It's the meditation technique that Wim Hof practice and teach in his workshops. As I mentioned some time ago, it's a mix of pranayama and tummo, but in a different manner (somewhat simpler imo).
The main focus of this method is to stimulate and strenghten the immunologic system. I am applying this meditation for two months (I'm still a beginner), and I feel some good improvements, not to mention a slow, but ever-growing resistance to colder temperatures.
He also has a book on this subject, called "Becoming the Iceman." I'd like to tell more about it, but I haven't readied it, so I think I'll just leave the torrent link where I found the ebook Link Removed here.
Hope it serves to anybody.
Namaste,
