"Many gods and men are eager to know
 what are the greatest blessings
 which can bring about a peaceful and happy life.
 Please, Tathagata, will you teach us?"
 
 (This is the Buddha's answer):

 "Not to be associated with the foolish ones,
 to live in the company of wise people
 and to honor those who are worth honoring-
 this is the greatest happiness.
 
 "To live in a good environment,
 to have planted good seeds
 and to realize that you are on the right path-
 this is the greatest happiness.
 
 "To have a chance to learn,
 and to be skillful in your profession or craft
 and to know how to practice the precepts and loving speech-
 this is the greatest happiness.
 
 "To be able to support your parents,
 to cherish your own family
 and to have a job that you like-
 this is the greatest happiness.
 
 "To live correctly, to be generous in giving,
 to be able to give support to relatives and friends
 and to live a life of blameless conduct-
 this is the greatest happiness.
 
 
 Discourse on Happiness 
 "To avoid doing bad things,
 to avoid being caught by alcoholism or drugs
 and to be diligent in doing good things-
 this is the greatest happiness.
 
 "To be humble and polite,
 to be grateful, and content with a simple life
 and not to miss the occasion to learn the dharma
 this is the greatest happiness.
 
 "To persevere and be open to change,
 to have regular contact with monks and nuns
 and to participate in dharma discussions-
 this is the greatest happiness.
 
 "To live diligently and attentively,
 to perceive the Noble Truths
 and to realize Nirvana-
 this is the greatest happiness.
 
 "To live in the world,
 with your heart undisturbed by the world,
 with all sorrows ended, dwelling in peace,
 this is the greatest happiness.
 
 "He or she who accomplishes this
 will remain unvanquished wherever she goes.
 Always he will be safe and happy-
 This is the greatest happiness."
