"The Greek word for "return" is nostos. Algos means "suffering." So nostalgia is the suffering caused by an unappeased yearning to return." - Milan Kundera

A person who longs to leave the place where he lives is an unhappy person.

Dreaming is not merely an act of communication (or coded communication, if you like); it is also an aesthetic activity, a game of the imagination, a game that is a value in itself. Our dreams prove that to imagine — to dream about things that have not happened — is among mankind's deepest needs. Herein lies the danger. If dreams were not beautiful, they would be quickly forgotten.

to have compassion (co-feeling) means not only to be able to live with other's misfortune but also to feel with him any emotion -joy , anxiety, happiness, pain
