Verse 68 [my interpretation]
A true warrior is not violent.
The strongest martial artist hides no anger behind his technique.
The greatest victor is not competetive.
Good employers serve their workers.
The best leaders make decisions in accordance with the will of the people.
Such persons are the embodiment of noncompetition;
they have no need for ego.
Instead, they know the virtue/power of using the skills of others;
Even “enemies” have much to offer them.
Since the ancient times,
our ancestors have known the virtue/power of being united with all heaven and earth.
When one recognises oneself as the Tao,
there is no one left to compete with.
