find a qualified teacher to help you, and "demons" will no longer be an issue. In the meantime, this might calm things down a bit:
In Qi Gong, when we open the superficial pathways of the meridians, some common initial sensations are pain, stiffness, heat, shaking and tingling in the muscles and limbs. These sensations emerge into our consciousness as we look for the roots to the obstructions in the pathways. With GENTLE natural practice and observation, the obstructions are gradually cleared, allowing for the next step in the development of virtue.
But what of the deep pathways of the meridians? How to clear those? Well, one answer is meditation.
Our minds are cluttered with many acquired influences. These include perceptions, thoughts, and habitual mental emotional states. Acquired influences can cloud the mind's innate influence on our selves and the world. In practicing meditation, many systems look towards clearing these acquired influences by re-establishing an awareness of the moment at hand. In doing so, the acquired influences naturally appear in stark relief to the landscape of true nature in the form of thoughts, perceptions, persistent mental-emotional states, even visions. Remember that these are acquired. Continue the work of maintaining awareness of the moment, and the obstructions will naturally clear away by themselves.
Clearing the deep channels is a natural process, similar to the opening of the superficial pathways, only these are the deep pathways, so the environment is different. Instead of opening the body, we open the mind and clear the obstructions within, allowing our innateness to manifest.
remember, GENTLE, NATURALLY OCCURING PRACTICE. NO FORCING!
