So you got your hands energized and you got that tingling sensation. That's the easy part. Most people can get it quickly, and all people can it with patience. The second part is difficult. We need at least one more energized point. Take your tingling hands as example, the second point can be your shoulders and/or your elbow. In Tai chi, an essential technique is loosening your shoulder and dropping your elbow (沉肩墜肘）. In between the two points, you have to relax everything. Master Wangxiangzai called it point-stretched-body-relax (點緊身松). In doing foot massage, the masseur creates one stretched point (at you sole, with pain) while you need to relax everything except where you create another stretched point. The best stretched point to use is your pelvic joint. In acupuncture, the acupuncturist takes care of everything, he creates at least two points with his needles and often times one will be in your hand. He twists his needles to create chi, you lie there and do not need to do anything. In all other chi disciplines, you also twist. Twist what? Your joints. In tai chi, it is called spiraling-force （or silk reeling 纏絲勁). Master Wangxiangzai called it eight direction tug of force (八面爭力).
They are all talking about the same thing. It is the best kept secret of our arts, for those who can't get it! Because they don't see it, can't experience it, therefore it is a secret to them.
