The heavy is the root of the light.
The still is the master of unrest.
Realizing this,
The successful person is
Poised and centered
In the midst of all activities;
Although surrounded by opulence,
He is not swayed.
Why should the lord of the country
Flit about like a fool?
If you let yourself be blown to and fro,
You lose touch with your root.
To be restless is to lose one’s self-mastery.
[From Change Your Thoughts – Change Your Life by Dr. Wayne Dyer]
