“If a man loses his reverence for any part of life, he will lose his reverence for all of life.”

Variant: Unlike a drop of water which loses its identity when it joins the ocean, man does not lose his being in the society in which he lives. Man's life is independent. He is born not for the development of the society alone, but for the development of his self.
