Well.. I've been into energy exercises for a long time now.. about 3-4 yrs, starting with NEW Energy Ways from Robert Bruce, and then also some soft qigong and meditation/yoga. Well lately i've been doing some "hard style" qigong.
Anyways.. In Marnia's book Cupid's there was a short paragraph on the side of a page on Energy Circulation.. Unfortunately there's no explanation as to how exactly "draw energy up the spine". It just says to do it..
