He who knows much about others may be learned, but he who understands himself is more intelligent. He who controls others may be powerful, but he who has mastered himself is mightier still.
Treat those who are good with goodness, and also treat those who are not good with goodness. Thus goodness is attained. Be honest to those who are honest, and be also honest to those who are not honest. Thus honesty is attained.
If you want to awaken all of humanity, then awaken all of yourself, if you want to eliminate the suffering in the world, then eliminate all that is negative in yourself. Truly, the greatest gift you have to give is that of your own self-transformation.
When the people of the world all know beauty as beauty, There arises the recognition of ugliness. When they all know the good as good, There arises the recognition of evil.
