The Deeper Symbolism of Freemasonry from The Meaning of Masonry by Walter Leslie Wilmshurst.

“There are members of the Craft to whom it is familiar, and who in due time may feel justified in gradually making public at any rate some portion of what is known in interior circles. But ere that time comes, and that the Craft itself may the better appreciate what can be told, it is desirable, nay even necessary, that its own members should make some effort to realize the meaning of their own institution and should display symptoms of earnest desire to treat it less as a system of archaic and perfunctory rites, and more as a vital reality capable of entering into and dominating their lives; less as a merely pleasant social order, and more as a sacred and serious method of initiation into the profoundest truths of life.” [via]
