In addition to what Shawn wrote,
Gently scan your aura, or bio-electromagnetic field around/through the body--a good way to do that is follow the steps to relaxing/opening the channels in Level 1's *Self Concentration* mentally go through each part of the body until you find the blockage. Shine your awareness through your body, almost as if your energy is a healing flashlight 'looking in the dark'.
look/feel for places that are stuffy or dense (too much Yang, or not enough Yin) or on the 'contrary' check *really subtle* places that don't seem related at all--sometimes these almost stand out, because they 'don't stand out' (too much Yin, or not enough Yang). Usually, if there's a 'block' somewhere, there's another place that is the 'seemingly opposite' they are both the 'energy block or deficit' and correlate to one-another. Clear one, and you correct the other--but sometimes being aware of/working with both might be necessary.
Other places worth noting:
- the head/neck, of course.
- the chest, or frontal part of 'the base of the neck'
You could also 'chant' the Mystical Symbol "OM" with your heart, radiating light and energy outwards, clearing your energy field and in doing that you might also find the blockage. Find the area that doesn't 'resonate' with Om and clear that area.
Om is a frequency that radiates outward into Infinity. (well, every frequency does--but Om is special in the aspect that it 'leaves no-one out') Sometimes, I've come across weird 'problems' that I couldn't correct fully unless I helped someone else's energy--don't concern yourself with this of course...but what I mean to say is; in your Om resonance, if you make the intention to help everyone (because your Om will pass through their fields anyways) then you will connect with the Divine OM. In that, your energy correction is greatly increased, when you've included Everything and Everyone. This goes along with what Chunyi mentioned in Level2 videos, if you do not 'have full love' in your soul, you cannot heal completely...and rather than stressing over the potential fact of 'you might not have enough' --just make the intention to help everyone as you are healing, and it not only covers 'all bases' but you increase your vibration as well...and in that, you can help others even more.
Energy/Mind has limitless applications, and sometimes, 'blockages' seem to persist due to the way we've unconsciously set them up. So, for practicality purposes I'll write something that's pretty effective as well. However, for simplicity, adhere to the Spring Forest System for the time being...since it covers a broad range of blockages, as well as the more specific. (that doesn't mean you *shouldn't* attempt variations or experimentation, as long as it's loving, simple and effective)
This technique is part of the "Classics" (Old-school systems)--at least I think it is...(otherwise I can't remember where I picked it up from...) Anyways, enough jabber on my part, here's the technique itself:
Gently sink your mind into the lower dantien (as if your dantien *is* where you are 'thinking from' --rather than 'from the brain down to the dantien') and let your energy shine really, really brightly--and no matter what comes up, no matter what thoughts arise... *stay* in your center until the problem diffuses.
Since all of your focus/energy is here, the 'energy problem' *has* to interact with your mind, if "it" wants to sustain it's continued 'existence'. (It doesn't really exist of course, energy is love, so we don't worry about 'intangible entities trying to 'get' your energy' ...it doesn't work that way.) Since the 'energy labeled as stinging/pain' is interacting with your mind, while in a state of 'BEing the dantien' -- it will naturally, either get *used up* 'as energy' or get 'caught up' in the natural process of your dantien recycling the energy of the body/mind.
Oh, and Small Universe can't hurt either.
