Henry Van Dyke - One World

"The worlds in which we live are two
The world 'I am' and the world 'I do.'"

The worlds in which we live at heart are one,
The world "I am," the fruit of "I have done";
And underneath these worlds of flower and fruit,
The world "I love,"--the only living root.

Henry Van Dyke
