The seal consists of a figure of Justice blindfolded, standing on the uppermost of three steps; in her right hand, she holds a pair of scales in equal poise; in her left, a sword; at the top, is the sun; beneath the scales are the Book of Holy Writings, and a square and compasses enclosing a trowel; at her right is a branch of acacia, a setting maul and spade.
These figures are intended to represent the reciprocal duties of the Grand Lodge and her subordinates. The sun, at the top, is emblematical of the light and intelligence diffused by the Grand Lodge; the three steps represent the degrees under her control; and standing on the topmost, with equal scales in her right hand, is to show that her first endeavor is to dispense justice impartially; her being blindfolded bids us remember that she does so without fear, favor or respect of persons;
the sword is to show she has the power to enforce obedience; but being in her left hand, it proves that she trusts rather to her subordinates walking by the square, circumscribing themselves by the compasses, and referring to the Great Book for guidance; while, for herself, she would prefer using the trowel with her right hand, to spread the cement of brotherly love and affection, rather than exchange it for the sword. The branch of acacia and implements are , as all Brethren know, emblems of morality, and of our hopes beyond the grave, and which are deeply impressed upon the mind of every one who gains admission within the inner enclosure of our temple. The legend around the circumference is, "Grand Lodge of Free and Accepted Masons, Michigan."
