D.H. Marks

“Fellow man! Your whole life, like a sandglass, will always be reversed and will ever run out again, — a long minute of time will elapse until all those conditions out of which you were evolved return in the wheel of the cosmic process. And then you will find every pain and every pleasure, every friend and every enemy, every hope and every error, every blade of grass and every ray of sunshine once more, and the whole fabric of things which make up your life. This ring in which you are but a grain will glitter afresh forever. And in every one of these cycles of human life there will be one hour where, for the first time one man, and then many, will perceive the mighty thought of the eternal recurrence of all things: — and for mankind this is always the hour of Noon.”
― Friedrich Nietzsche

“The Dalai Lama, when asked what surprised him most about humanity, answered "Man! Because he sacrifices his health in order to make money. Then he sacrifices money to recuperate his health. And then he is so anxious about the future that he does not enjoy the present; the result being that he does not live in the present or the future; he lives as if he is never going to die, and then dies having never really lived.”
― Dalai Lama
