It is by death that we live, because we exist today only for having died to yesterday. It is by death that we hope, for we can believe in tomorrow because we're sure today will die. It is by death that we live when we dream, since to dream is to deny life. It is by death that we die when we live, since to live is to deny eternity! Death guides us, death seeks us, death accompanies us. All that we have is death, all that we want is death, and death is all that we care to want."
----Fernando PessoaIn other words: Death.
