Also, it is hard to change direction once a person begins to move. With Tahn Bong Sul, in the beginning, the student is taught to wait for the opponent to make the first move so he will be easier to neutralize. Correct body movement is taught in order to increase the student's ability to move quickly with balance, speed and power. The next factor to take into account when learning Tahn Bong Sul is the centralization of KI power. There are two types of power, external and internal.
External power comes from developing strong muscles.
As time passes, a person's physical strength will diminish. Yet, internal strength, if proper training is maintained, will increase with age no matter how old a person becomes. Learning to centralize one's KI will greatly increase the power of the techniques of Tahn Bong Sul, giving the practitioner not only power but confidence and control. The tahn bong is a universal defensive weapon which can be found almost anywhere, yet by many, never seen. Its techniques are natural, fluid and practical.
