The Two Methods of using the Waist aka Dantian to add power into a strike/ attack
Holding these muscles in an isometric (Baozhang lit. Holding Extending) manner is called building a Dantian. As the muscles of the abdomen are becoming stronger they will also naturally become thicker all the while developing a more spherical shape of the transversalis fascia etc. As these physical developments become more and more distinct the two methods/functions of the waist will have a greater potential to impart a power that has a greater affect on the other parts of the body, transferring power from the legs while also imparting a counterforce back into the legs, coordinating abd/ or being transferred via the movements of the Shen (upper torso- ribs, thoracic vertebrae, shoulder blades and muscles of the chest and upper back), and then reaching the arms and into the (Shou Fa). The arm methods are vast in number and there is no real limitation on the number of them. There are two primary methods in the chest (Ting and Han- Upright and Hollowing/ Expanding) but these can lead to numerous sub methods of upper torso. The leg methods also have two distinct and primary methods (Deng and Beng- Straightening and Bending) but can also have many sub methods. The waist however is said to only have two methods - turning on its axis(’s)/ axes (Heng) or moving the center point of the axis of and down (Zheng).
The method of turning on its axes is relatively easy to figure out and a more naturally derived function. The second method is considered unnatural and is counterintuitive because in order to be executed in the correct manner the lower half of the spine is moving against the direction that you naturally think the momentum of force is going. This second method needs to be practiced in an extremely abrupt tucking of the tailbone, which drives the Dantian upward. This should be understood to as- a quick and powerful movement of a lot of flesh and fairly significant portion of body mass, driven upwards to start a shockwave like movement of the flesh that travels up the back, through the shoulder and finally down to the arm and reaching the hand or attacking part of the body. Practicing individual or consecutive strikes using this second method ofvthe waist/ dantian is called ‘Fa Li Fali / Practicing with Power(“Practicing with Power”/Emitting or Discharging Power). Practicing this method while moving slowly and without the quickness or abrupt movement of the tailbone but trying to move it smoothly and in coordination with the rest of the body is called ‘Huadao fa’ Huadao / The Learning Speed (The learning speed/ drawing the path (of power) through the body). In the videos of ysb and various instructive materials this practice has been translated as’the Learning Speed’ which is apt in a certain sense, although it’s through a mixture of practicing the method while moving fast and then refined by the doing it slowly, so that one truly learns the movement. And once the movement to generate the Fa Li’ is understood and can be done fluidly and in harmony with the other body methods, is when you will want to devote even more time to the slow practice as it strengthens the ligaments and connective tissues while strengthening the muscles used to maintain or hold the body in various postures so that the fast movement can function more efficiently.
The movement of the lumbar and tailbone to drive the dantian upward begins to feel like a powerful mechanism when the vertebrae and sacrum begins to become a single unified action. This abrupt powerful movement is given the analogy of being like a bow ‘gong’ (as in bow and arrow) and it begins to feel like the lumbar is the bow but the string is also constantly pulled/drawn, or rather that the bow is drawn and when the action of the tailbone tucking is done, the bowstring is ‘Released/ the arrow(power) is emitted’ (Fa). Coordinating and harmonizing the Yao with the Shen (upper torso, which is also likened to be its own bow) is called ‘unifying the two bows into one’ (er gong yi gong he (grm?)). Which is another major achievement on one’s path of learning. Getting back to the difficulty and unnaturalness of learning this is described in a classical Internal Martial art saying- “The new student is to be kept locked inside the school for two years.” Which is the roughly two to three years of practice required to fully harmonize all these individual methods of the body into a single method (Zhengti fa), and that until this method of using the tailbone is understood it will have no use to you when getting into a fight and trying to use it in a fight before it’s fully realized will likely cause you to lose said fight. It’s like baking a bread where it has to be properly mixed, kneaded, leavened and then baked in the oven and dried before it could be
be used as an improvised weapon to hit someone over the head with.
So after one has a really excellent grasp of this movement and can employ the ‘Fa’/ Release the string' in a few movements then they can practice in the manner where the Release is held back meaning the sacrum is maintained in its neutral position throughout the execution of the whole martial movement/ technique, and continued to be held back whike smoothly flowing into the next technique and so on, all the while feeling the tension on the back bow building up greater and greater with each consecutive technique. This is ‘Hunyuan Lian’ (Flowing practice) and is where solo is at its closest approximation of an actual fight while using the whole body method of Bagua as an Internal Martial art. In an actual fight while using Bagua/ Ysb it would be an interplay of Smooth flowing movements and intermittent Releases of power, and any myriad variations of something inbetween. One strike using a Release could end the fight right away or dozens of flowing movements and never needing to release could be enough to finish the fight. In the practice however, you will feel a strong urge to release the power at several times during the striking drills or form but in the spirit of this practice method you should try to refrain from releasing and absorb or contain the power within your own body as another meaning of Hunyuan is the last final touches of perfection being put into your practice, or the ultimate level of refinement.
So to briefly touch on the reason why this is developed and how it would be applicable in a martial art there is a saying that 'Power (Jin) travels close to the bones'. So imagine that when a bone, like the bones of the forearm, moves quickly to punch the hand out, all the flesh that surrounds and is attached to the bone is left behind due to inertia. The strike is hitting only with the bones of the arm while the mass of flesh that is attached to the bones is still catching up. But by properly using the Fa Li/ Jin (Jin is refined or trained power, while Li denotes raw power), to move first, yet only fractions of a second, before the arm moves, the flesh is motivated to be moving in time with the bones, hence 'Jin travels close to the bone'. This is a tangible feeling and the bread and butter of practicing to FaLi / Fajin. And a major portion of one's time is spent on the finding the timing to get the wave to properly make it all the way out to the hand. Often times it fades off in the back, shoulders or elbow, but with practice one can eventually succeed in getting the wave to arrive with the hitting of the striking hand/ arm. In standing in place striking this can be relatively easy, so the next obstacle to overcome is during the moving-stepping strike drilling practices, where the key is getting the moving foot to be landing on the ground, just as the wave is arriving at the striking hand. If the foot lands first the power will still arrive at the hand but it's not an effective technique as it's a one two, instead of both the upper and lower body hitting to cause a scissor effect (one one 1:1) and the power will be half drained into the leg. If the foot lands after the hand arrives then the power is not considered complete for the technique. Roughly 98% of the striking techniques in Ysb require this, what is called 'Waist, Hand, and Foot Harmony' or Waist, hand and foot arrive at the same time. The other 2% is more advanced striking techniques where the foot intentionally arrives after the hand and waist because the opponent's body is being used to act like your other foot and the strike will ground out through the opponent.
With practice you will also begin to learn how relaxation and tension in the body can direct and change the nature of the power, which is a major part of distinguishing the 8 attacking methods from one another, aside from the obvious differences in hand shapes and or hitting parts of the arm being used. The 3 basic strikes (Also known as the Lao San Zhang 'Old Three Palms') from each striking method are very basic or fundamental movements where one can focus solely on developing the power of waist. Try to learn how to 'FaLi' in the 3 strikes before moving onto the other strikes inside the method as they will then be easier to learn.
I hope this helps out. Use this post in combination with my other posts on using the spine and dantian to add FaLi to the striking technique (Either Bolangjin (Crashing Wave Power) or Zhedie Jin (folding power)), but ultimately find the analogy that works for you.
