“The Marriage of the Sun and Moon: This takes place in man when the heart and mind are joined in eternal union. It occurs when the positive and negative poles within are united, and from that union is made the Philosopher’s Stone.” – The Initiates of the Flame Manly P. Hall pg. 40

The dual principle of “male” and “female” [in Masonic teachings] is represented by the “square and compass.” The “compass” represents OSIRIS, the male god of the Egyptians, while the “square” is the symbol representing ISIS, the female goddess of Egypt – both are sexual symbols.
