The following are all attributed to the Buddha
A dog is not considered a good dog because he is a good barker. A man is not considered a good man because he is a good talker.
A family is a place where minds come in contact with one another. If these minds love one another the home will be as beautiful as a flower garden. But if these minds get out of harmony with one another it is like a storm that plays havoc with the garden.
A good friend who points out mistakes and imperfections and rebukes evil is to be respected as if he reveals a secret of hidden treasure.
A wise man, recognizing that the world is but an illusion, does not act as if it is real, so he escapes the suffering.
All that we are is the result of what we have thought. If a man speaks or acts with an evil thought, pain follows him. If a man speaks or acts with a pure thought, happiness follows him, like a shadow that never leaves him.
An insincere and evil friend is more to be feared than a wild beast; a wild beast may wound your body, but an evil friend will wound your mind.
Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense.
Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment.
Do not overrate what you have received, nor envy others. He who envies others does not obtain peace of mind.
