Hi Mike,
It's actually true, but nobody is capable.
I'll tell you from the perspective of my system. The techniques themselves are important, but not quite in the way that people believe they are. They are simply examples of how to apply the principles and the foundation of our system, and are not an end in and of themselves. They are useful, but are not THE POINT of training. If you understand the principles and the foundation of our system, then every single movement that you make, whether it's a proper "technique" or not, can be a devastating technique. And understanding that issue is far more important than cultivating a list of techniques.
The principles and foundation of our system are actually pretty simple: strong root, use the rooted stance to drive body rotation, and use full-body engagement thru the rotation to apply all techniques. That is really it, and that gets taught, or at least explained, very quickly.
The problem is, it takes a lot of work before anyone really understands what this means and how to use it effectively, and to develop a level of real skill with it. But at least in theory, if one had the vision to fully understand what this means from the first day, then that is all the instruction that one would need.
The techniques and the forms are taught as a way of training these principles into the body, as examples of how the principles are used. Nobody has the vision to fully understand this from the beginning, everyone needs to go thru the process of learning and training and drilling the techniques before this comprehension arises. Once that training has been accomplished, then one can understand that the entire system is contained in a very few basics and principles and foundation.
With our system, one does not need to learn much in order to be able to fight, as long as one properly understands what they have learned. And a brighter student will arrive at that understanding after learning less of the curriculum than a less bright student. One could become very very competent and skilled with our system with just a small amount of material, if it is properly understood and properly trained. In my opinion, the later material is there as additional examples for training, and my Sifu has even said as much. If you wish to be a teacher, then you cannot predict how much material a student must learn before he "gets" it. One student might get it after learning a little bit, but another student might need to learn more before he gets it. And other students may never get it, even if they learn all of it. But if you get it, then honestly you do not need to learn more, at least not for yourself. If you wish to be a teacher, then you should learn more in case your students need it.
So yes, one can learn the principles of our system quickly. But reality shows us that it takes a long time and a lot of training to fully understand what it is all about.
