"Don't think they are mean, but watch out for yourself."

This Taekwondo man, who knows what is right and what is wrong, becomes ethical naturally and the ethical behavior is to discern what is right and what is wrong, and to choose what is right and abandon what is wrong.

It is same with the way of Haneul(Heaven) in activity of body. The principles of using body is same as that of using mind.

What you should look out for at first, looking out for everything with piousness, is your self.

In this manner, you as Taekwondo man do both of erasing and picturing yourself at once, so you are everywhere yet with non-being and you are nowhere yet full of being. Then, wherever you are your position is necessary while whenever you are not that place should be emptied, everything of which be precise with no conflict at all. This is to get your proper position on the lookout for environment and to get the world even in the lookout for the world.
