You basically sit there meditating waiting for something to happen. Now, as to what MAKES IT HAPPEN; "emptyness of the mind." Daoist and Buddhists, hold the view that the soul is already powerful, the thing that prevents us from taping into that well of power is the garbage in our mind. Here is an analogy; imagine, you have 500 lbs of garbage on your back. Lets asume for a moment you are able to carry it, albeit with great difficulty.
You walk around with it everywhere; sure, you would get anywhere much faster if only you weren't carrying that stuff but, sadly, you just will not put it down. Its heavy, its burdensome, but you just will NOT put it down. Now, why won't you put it down? Because, you've been carrying it your whole entire life.
Daoist mystics believe that chi is already constantly flowing in your body, and when you do something as mundane as wiping your rear after taking a dump, you are directing chi to that part of your body. What? Even masters of chi have to use the bathroom you know. If you are interested in meeting a Daoist mystic be warned, they stink to high heaven, as most live like homeless people. They take meditation so seriously they never bathe. Miyamoto Musashi, Japanese history's most powerful swordsman, was said to have never bathed. Musashi, spent virtually all his time living in the wilderness, his mornings would begin with basic Kenjutsu, and his day would be dominated by almost nothing but meditation. Ocassionally when he got lonely he would visit a brothel or two but as soon as he was done, he would return to his cave to meditate.
Anyway; how vigorously your chi flows, is rooted in whether or not your mind has been cleared of garbage. If your mind is garbage free from constant "blanking out" while meditating, the chi flows on its own, and you do not actively focus, its direction is something that happens naturally. At least that is the view held by Daoists; I am not aware of the methods used by the Shaolin temple, Yogis in India, or modern day British Druids. Oh yes the Druids are still around; you need to be careful though, as in modern day England there are modern drug addict hippie new age whack jobs who claim to be Druids, but they're not. Being a Druid, to take that religion seriously requires SEVERE discipline, I am not aware of what goes into it specifically as the order has been historically secretive.
