TAO: That in virtue of which all things happen or exist. The rational basis of human   activity or conduct. A universal, regarded as an ideal attained to a greater or lesser degree by those embodying it. From Chinese TAO “way, path, right way (of life), reason”

TAO = DO = Way of life!

When we look beyond the kicking and punching we see that Traditional Taekwon Do is much more. Its focus is on building the individuals character regardless of religion, sex, or race. There for the physical aspect is only a small part of the individual being on the right path.
