"What is it, when all is accomplished, that still binds the Masters to the world of men ? Not anything that the world can offer Them. There is no knowledge on earth They have not; there is no power on earth that They wield not; there is no further experience that might enrich Their lives; there is nothing that the world can give Them, that can draw Them back to birth. And yet They come, because a divine compulsion that is from within and from without sends Them to the earth — which otherwise They might leave for ever — to help Their brethren, to labour century after century, millennium after millennium, for the joy and service that make Their love and peace ineffable with nothing that the earth can give Them, save the joy of seeing other Souls growing into Their likeness, beginning to share with them the conscious life of God."
