Here's the story.
Here the book.
Sow flowers so your surroundings become a garden
Don’t sow thorns; for they will prick your feet
If you shoot arrows at others,
Know that the same arrow will come back to hit you.
Don’t dig a well in another’s path,
In case you come to the well’s edge
You look at everyone with hungry eyes
But you will be first to become mere dirt.
Humans are all one body,
Whoever tortures another, wounds himself.
