"What you are now is the result of what you were. What you will be tomorrow will be the result of what you are now. The consequences of an evil mind will follow you like the cart follows the ox that pulls it. The consequences of a purified mind will follow you like your own shadow. No one can do more for you than your own purified mind - no parent, no relative, no friend, no one. A well-disciplined mind brings happiness."
