"Is any larger bounty conceivable than this...that an individual...become the cause of peace and well-being, of happiness and advantage to his fellow men?"

House of the Master, 7 Haparsim

"And the honor and distinction of the individual consist in this, that he among all the world’s multitudes should become a source of social good. Is any larger bounty conceivable than this, that an individual, looking within himself, should find that by the confirming grace of God he has become the cause of peace and well-being, of happiness and advantage to his fellow men? No, by the one true God, there is no greater bliss, no more complete delight."
