try moving your energy about your body as you meditate. not "raising" energy, but moving it; like from your legs to an arm, from that arm to your stomach, from you stomach to your head, from your head to one of your legs, etc. just ignore the chakras and start moving the energy.
then, when you have felt the energy at times other than when others move into your energy radius, you can try to start affecting the physical with it. a useless but neat trick i picked up (actually the first indication that the energy was real and i wasn't just insane) was when i was able to flow energy into little papers that were floating down the street, and then forcing the energy of the paper to "attach" itself to the ground. the paper stayed exactly where i stopped it, even when a bigger gust of wind came through. kinda freaked me out until i broke down my original thoughts about how the world works. eventually i even got to making wind blow by using energy like a giant hand; pushing the air to generate wind.
the world becomes more wonderful and more frightening with the more you understand.

Secret of Secrets
At first, I worried that my energy was something which could only be used for myself. Then it seemed like it was not of much good to myself and even just to feel it I needed a person of lower energy to move it into. Now it seems like the best results I get are from giving my energy to other people with no expectations of results. The strongest expectations come from needing results to prove energy to other people.
