Buddha

"Do not overrate what you have received, nor envy others. He who envies others does not obtain peace of mind."

"The world, indeed, is like a dream and the treasures of the world are an alluring mirage! Like the apparent distances in a picture, things have no reality in themselves, but they are like heat haze."

"To be idle is a short road to death and to be diligent is a way of life; foolish people are idle, wise people are diligent."

"If a man's mind becomes pure, his surroundings will also become pure."

"If a man possesses a repentant spirit his sins will disappear, but if he has an unrepentant spirit his sins will continue and condemn him for their sake forever."

"Whatever words we utter should be chosen with care for people will hear them and be influenced by them for good or ill."

"All things appear and disappear because of the concurrence of causes and conditions. Nothing ever exists entirely alone; everything is in relation to everything else."
