" And again, though we cannot prove, we feel, that we are deathless. We perceive that life is not like those dramas so beloved by the people—in which every villain is punished, and every act of virtue meets with its reward; we learn anew every day that the wisdom of the serpent fares better here than the gentleness of the dove, and that any thief can triumph if he steals enough. If mere worldly utility and expediency were the justification of virtue, it would not be wise to be too good. And yet, knowing all this, having it flung into our faces with brutal repetition, we still feel the command to righteousness, we know that we ought to do the inexpedient good. How could this sense of right survive if it were not that in our hearts we feel this life to be only a part of life, this earthly dream only an embryonic prelude to a new birth, a new awakening; if we did not vaguely know that in that later and longer life the balance will be redressed, and not one cup of water given generously but shall be returned a hundredfold? "
