On the Level in Freemasonry's principle

The Level serves both as a symbol of human equality and a moral instruction on the passage of time. As an emblem of equality, the principle of meeting on the level signifies that all members are equal, with no brother considered more important than another, reminding brethren to practice humility regardless of rank or position, as an article on the Regional Grand Lodge of Northern India's website notes.

In monitorial instruction, the Level is also designated as one of the working tools of a Fellowcraft, used by operative builders to lay the courses of a wall straight and even 1. Symbolically, the tool teaches that Masons build upon the level of time 1. Unlike a physical wall, which an operative mason can dismantle and reconstruct if built poorly, human actions erected upon the level of time cannot be unbuilt once past; an opportunity lost on this level is gone forever 1.
