Heavy is the origin of lightness,
and tranquility is the ruler of acting rashly.
Therefore when the wise person travels in the world
he never loses sight of his heavy load,
even when he sees magnificent sights.
He dwells in peace, unattached.
How can you be said to be a wise person,
if you behave frivolously in front of everyone?
To be frivolous is to be separated from the source,
just as acting rashly means you have lost control of yourself.
-Lao-tzu- (Tao Te Ching, verse 26, interpretation by Robert Brookes)
