How's this for an excellent quote?
Our Rebbe revives the dead. What is a corpse? Something cold and unfeeling. Life is movement, warmth, excitement. Is there anything as frozen in self-absorption, as cold and unfeeling as the mind? And when the cold-blooded mind understands, comprehends, and is excited by a G-dly idea - is this not a revival of the dead?
— The disciples of Rabbi Schneur Zalman of Liadi
