Presumably, as a Martial artist, I do not fight for gain or loss, am not concerned with strength or weakness, and neither advance a step nor retreat a step. The enemy does not see me. I do not see the enemy. Penetrating to a place where heaven and earth have not yet divided, where yin and yang have not yet arrived, I quickly and necessarily gain effect.
