Everyone thinks of changing the world, but no one thinks of changing himself.
If you want to be happy, be.
Happy families are all alike; every unhappy family is unhappy in its own way.
All, everything that I understand, I understand only because I love.
The two most powerful warriors are patience and time.
There is no greatness where there is no simplicity, goodness and truth.
Truth, like gold, is to be obtained not by its growth, but by washing away from it all that is not gold.
In the name of God, stop a moment, cease your work, look around you.
We can know only that we know nothing. And that is the highest degree of human wisdom.
The sole meaning of life is to serve humanity.
