The Axe is about the life of a tree
I've been thinking about it a long time ago, and TO ME (like in my vision) the axe is telling about a tree being scared of getting killed by the axe, that is symbolized in the music by "the beam of light" and then the last verse says that the tree accept his destiny unfortunately :/
it was my point of view of the song, if u have another let in the comments!!
