From The Dhammapada:

 

We are what we think.

All that we are arises with our thoughts.

With our thoughts we make the world.

Speak or act with an impure mind

And trouble will follow you

As the wheel follows the ox that draws the cart.

 

We are what we think.

All that we are arises with our thoughts.

With our thoughts we make the world.

Speak or act with a pure mind

And happiness will follow you

As your shadow, unshakable.
