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

“In some Masonic Lodges the candidate makes his first entrance to the Lodge room amid the clash of swords and the sounds of strife, to intimate to him that he is leaving the confusion and jarring of the religious sects of the exterior world, and is passing into a Temple wherein the Brethren dwell together in unity of thought in regard to the basal truths of life, truths which can permit of no difference or schism.” [via]
