"Hardship often prepares an ordinary person for an extraordinary destiny."

"If we find ourselves with a desire that nothing in this world can satisfy, the most probable explanation is that we were made for another world."

"Friendship is born at the moment when one man says to another "What! You too? I thought that no one but myself."

"Friendship is unnecessary, like philosophy, like art. It has no survival value; rather it is one of those things which give value to survival."

"If nothing in this world satisfies me, perhaps it is because I was made for another world."

"If you live for the next world, you get this one in the deal; but if you live only for this world, you lose them both."
