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. 
How can a troubled mind 
Understand the Way?

Your worst enemy cannot harm you 
As much as your own thoughts, unguarded.

But once mastered, 
No one can help you as much, 
Not even your father or your mother.

~ The Buddha as recorded in the Dhammapada
