Tao Te Ching Chapter 65
The ancients who knew how to follow the Tao
Aimed not to enlighten the people.,
But to keep them ignorant.
The reason it is difficult for the people to leave in peace
Is because of too much knowledge.
Those who seek to rule a country by knowledge
Are the nation's curse.
Those who seek not to rule a country by knowledge
Are the nation's blessing.
Those who know these two (principles)
Also know the ancient standard,
And to know always the ancient standard
Is called the Mystic Virtue.
When the Mystic Virtue becomes clear, far-reaching,
And things revert back (to their source)
Then and then only emerges the Grand Harmony.
