Who is a mason? A mason, particularly in the context of Freemasonry, is defined as one who has been initiated into the mysteries of the Fraternity of Freemasonry. The term 'freemason' itself is believed to be connected to 'freestone', which refers to a type of stone that can be easily worked and shaped. Historically, the term distinguished skilled craftsmen who were free to work with this stone from those who were not. Freemasonry is often described as a system of morality, a philosophy of life, and a means of advancing one's spiritual interests through the practice of brotherhood and moral principles. It is a society that aims for moral perfection based on equality and fraternity among its members.
