Wow...people came back to this in 2017? Cool! This never personally worked for me, but I really didn't put in the effort. I really want to believe all this, and I still kinda do, but I have one qualm with the entire business: why have we never heard of people doing this before? Wouldn't it be all over the news if people could do this? And yeah, I get that most people would want to keep their ability secret for honor's sake, but there's bound to have been one person, in all of history, who came out and demonstrated, "Yeah, I can control [air/water/earth/fire] with my mind."
But I still do believe that this stuff is possible. I'm not sure it's the path for me to go down, though, but I find myself trying to channel Chi most times I'm bored. It's never in the proper circumstances; still, though, about four years since this thread came out, and I'm (somewhat) sticking to it.
