What, the curious Freemason asks, has the Yggdrasil to do with Freemasonry? In the first instance, it is a symbol of something, and we Freemasons enjoy a good romp through symbol dissection. Second, Freemasons have their own tree, and it is interesting the symbolism that coincides and collides when we look at the two motifs. The Tree of Freemasonry is the acacia (Western), or in Latin, Acacia Vera or vachellia tortilis. The tree is an evergreen tree, common in warmer climates, and is found in Africa, the Middle East, and other temperate climates. The tree’s wood is used to build weapons and furniture, and its resin is used in incense and perfumes. Biblically, it is referred to as the shittah tree and was the wood Moses used to build the Ark of the Covenant and it was used in the construction of the Tabernacle. While it has many practical uses, I see there is one reason it is such a symbol of immortality: it is an evergreen.
THE Flaming Sword, more popular in literature than perhaps in actual use or fact, seems to be symbolically related to several key concepts, all appropriate to the office of the Tyler, or guardian of the Temple entrance. It may represent that only those that hold Truth or Wisdom may enter holy places or stand in the presence of that Truth.
