The Deeper Symbolism of Freemasonry from The Meaning of Masonry by Walter Leslie Wilmshurst.
“And mark that of those jewels some are said to be moveable and transferable, because when displayed in our own lives and natures their influence becomes transferred and communicated to others and helps to uplift and sweeten the lives of our fellows; whilst some are immoveable because they are permanently fixed and planted in the roots of our own being, and are indeed the raw material which has been entrusted to us to work out of chaos and roughness into due and true form.” [via]
