How do we know whether we are practicing correctly?

Answer by Grandmaster Wong Kiew Kit
This is a very important question. Not only it enables us to avoid wasting time, but also increases our cost-effectiveness.
We know we are practicing an exercise correctly when we have the effects practicing that exercise will give. At a longer scale, we know we are practicing an art correctly when we have the results practicing that art is meant to give.
For example, we know we practiced “Lifting the Sky” correctly just now because our objective in that practice session was to generate a chi flow, and we had a chi flow.
In our case because we practice high-level chi kung and we are cost-effective, we have the expected effects immediately. Other practitioners will need a few months before they know whether they have the desired effects.
We know we practice chi kung correctly because we enjoy the benefits that practicing chi kung is meant to give. Practicing chi kung is meant to give good health and vitality. We have good health and vitality after a few months of our chi kung practice. Other practitioners who practice a lower level of chi kung or are less cost-effective will need a few years.
But a lot of chi kung practitioners still remain sick and weak despite practicing chi kung for many years. They did not ask the question you did, or else they would know, if they were courageous enough to admit to themselves, they had not been practicing genuine chi kung. They would not have wasted many years.
Alternatively, the art they practice may be genuine but they are not practicing correctly, or else they would have obtained the results the art is meant to give. Had they asked the question, they would have been more cost-effective in their practice.
