Sit and release any effort in your body especialy in your 3rd chakra.
This will increase your energy flow because it is effort that blocks the the flow of energy.
This nurish your entire energy system.
Another way to increase your energy is to concentrate on the energy body, and by focusing on your energy body you will raise your vibration and release blockeges.
Just to play devil's advocate for a second...
How exactly do we know this?
What I mean is, do you know this because someone told you? Or because you have direct experience with it?
And how do you know it's "increasing your energy flow"?
I've read in a book that effort and tension blocks the flow of energy in the body, so I started to release
the effort & tension in my body. Then I began to feel an increased flow of energy in my body.
And you may have heard or read that when you concentrate on the chakras it builds energy in them, so I figure the same goes for the energy body
Well, it's definitely true that when you relax your body that you unlock quite a bit of potential. I see it every time I practice Aikido. We work towards always being relaxed while practicing, as you have much more tactic response to work with. It's easier to "feel" attacks against you when you're relaxed.
As for the energy/chakra thing... I really have no comment. :)
I don't do anything with those. hehe
