A tree that can fill the span of a man's arms grows from a downy tip; A terrace nine stories high rises from level earth; A journey of a thousand miles starts from beneath one's feet.

The sage avoids extremity, excess, and extravagance.
Abandon cleverness, discard profit, and thieves and robbers will disappear.
