Step 1: The Ordinary World - This is where the hero exists before his adventure begins. The hero is oblivious to the adventure to come. In general, this part of the monomyth humanizes the hero so that we can identify better with them and empathize with them during their journey. This is Harry prior to getting his invitation to attend Hogwarts. Masonically, this would be a candidate prior to petitioning a lodge.
Step 2: The Call to Adventure – This is where the hero receives the invitation for his adventure For Harry, this occurs when Hagrid shows up at the Dursley’s doorstep with his invitation to Hogwarts in his hand. Masonically, this represents the candidate when he decides ultimately to petition a lodge, undergoes his investigation, and ultimately is accepted to receive his degrees in Freemasonry.
Step 3: Cross the First Threshold – When the hero enters the world which is foreign to him. This occurs when Hagrid brings Harry to Diagon alley and to Gringots, he introduces him to the wizarding world. Masonically, this occurs when the candidate knocks 3 times on the door of the preparation room and enters the lodge for his first degree.
Step 4: Trials, Friends, and Foes – Just as it suggests, the hero has trials, meets allies and his foes. In the Sorcerer’s Stone, Harry meets Hermoine and Ron, they make it past Fluffy and enter the trap door in the forbidden corridor, together overcome the obstacles in their path, allowing Harry to confront Voldemort for the 1st time, who has partially possessed Prof. Quirrell. You continue to see Harry repeat this step in the subsequent novels where he overcomes obstacles with the aid of his allies. Masonically, this represents the candidate who is received by the Senior Deacon, who leads them around the lodge, where they are challenged by the Junior Warden, Senior Warden and Worshipful Master.
Step 5: Magical Mentor (or the Mentor with Supernatural Aid) – The hero meets an older and wise mentor, often with magical powers and/or possessing a magical object. In the Harry Potter novels, Dumbledore fills this archetype (giving Harry the Invisibility Cloak in the Sorcerer’s Stone), however Sirius Black (Gives Harry the Firebolt Broomstick) and the other members of the Order of the Phoenix, and Dobby (gives Harry the Gillyweed in the Goblet of Fire) also act as Mentors for Harry. Masonically, the Senior Deacon would fulfil this role, as the Senior Deacon who escorts the candidate around the lodge, and assists the Worshipful Master with the candidate at the altar where they take their obligation, receive the due guard, sign, pass and token of each degree.
Step 6: Dragon’s Lair – When the hero crosses a second threshold, he faces a significant physically and psychological risk. This would be represented by Harry’s journey to his second confrontation with Voldemort at the end of the Goblet of Fire, where upon touching the triwizard’s trophy at the same time as Cedric Diggory, it reveals itself to be a portkey, bringing them both to a graveyard where his blood is used to reconstitute Voldemort. Masonically, this would be when the candidate takes his steps toward the altar, to undertake his obligation.
Step 7: Moment of Despair – The hero is close to defeat, and he has to dig deep inside himself to be able to escape the moment. In the Goblet of Fire, Harry uses knowledge he has been taught (the disarming spell) to counter Voldemort’s killing curse. The wands are connected, and the spirits of Voldemort’s past victims emerge from his wand. Once the connection is broken, the spirits remain, protecting Harry and allowing him time to grab Cedric’s body and escape by grabbing the trophy. Masonically, this can be thought of when the candidate takes his obligation. He must honor the obligation every day for the rest of his life, or face the penalty of his obligation.
Step 8: Ultimate Treasure – The hero receives a prize for successfully escaping from his moment of despair. The reward can take on many forms, however it normally is secondary to the personal transformation the Hero undergoes. For Harry, the second confrontation with Voldemort transforms him, helping instruct Defense Against the Dark Arts to Dumbledore’s army in the Order of the Phoenix, as well as giving him courage to face the obstacles ahead of destroying the horcruxes and defeating Voldemort . Masonically speaking, the reward given to a candidate is the password, grip or token, due guard and sign, how to wear their apron and their working tools, as well as the explanatory lectures and charges for that degree, but also the transformation that takes place where the candidate becomes a brother.
Step 9: Homeward Bound – This represents a retracing of the hero’s steps in reverse order. This means that once again the hero must face challenges, resolve to defeat his enemy and return home. There might be a moment where the Hero is forced to choose between personal objectives, or to answering to a higher cause. For Harry, this covers the events of The Deathly Hallows, where Harry and his allies hunt Horcruxes, they are captured, escape, and ultimately Harry faces Voldemort for the last time. Masonically, this can be thought of as the beginning of the second section of the third degree, where the candidate represents Hiram Abiff, and the three ruffians attempt to pry the secrets of a Master Mason from him.
Step 10: Rebirth & The Champion’s Return – This is the climax of the hero’s journey, where he faces his final and most difficult encounter with death and returns back to the Ordinary World changed. For Harry, this occurs when he goes to the Forest encampment outside of Hogwarts and allows Voldemort to kill him. He wakes up in a dreamlike version of Kings Cross Station, where he meets Dumbledore and learns that he hasn’t died. He learns that the protective charm his mother Lily placed on Harry is kept alive inside of Voldemort, because Voldemort used Harry’s blood to reconstitute himself. Thus, Voldemort could not kill Harry, and Harry can now go back and finish him off. In Masonic terms, I think this is pretty self-explanatory to those that have gone through the 3rd degree. There is a deeply moving and profound thing that happens which transforms the candidate.
