Past masters took many years to attain energy flowing at the five levels, but we can attain this in just four hours! How is it possible?
— Lukas, Germany
This is ridiculous but true.
There are two main reasons.
Past masters did not differentiate between techniques and skills, whereas we do. They practiced any techniques they were taught when they were students. When conditions were ideal, they developed the necessary skills, often without their conscious knowing. These ideal conditions happened infrequently even when they practice every day. Over a long period, like after many years, they accumulated enough results, which happened haphazardly, to feel energy flowing at these five levels.
Let us take an analogy. In this course, many students come from other countries, like from England, Austria and Holland. If they do not have the right techniques, like a car or a train, and do not have the right skills, like traveling along the correct routes, but just travel haphazardly even they travel everyday they will take many years to arrive at Frankfurt if they ever do. But they took only a few hours to arrive because they have the right techniques and the right skills, i.e. they drove a car or took a train, and travelled along the right routes.
Secondly, instead of developing the necessary skills on their own, which would take at least few months, I transmitted the skills to them so that they could get the benefits immediately.
Is there any difference between Golden Bridge and Bone Marrow Cleansing at Muscle Level in developing internal force?
Yes, there is some difference. The force developed in Golden Bridge is colsolidated, whereas the force developed in Bone Marrow Cleansing at Muscle Level is relatively more flowing.
It is significant to note that the comparison is relative. Bone Marrow Cleansing at Muscle Level is more consolidated than many other methods of force training, but compared to Golden Bridge it is more flowing.
As a rough guide the proportions of consolidating and flowing are as follows in the following force training methods.
Golden Bridge 90-10
Bone Marrow Cleansing at Muscle Level 85-15
Iron Wire 80-20
Flower Set 50-50
108-Pattern Yang Style Taijiquan 10-90
