In laying out the monomyth, Campbell describes a number of stages or steps along this journey. (1) The hero starts in the ordinary world, and receives a call to enter an unusual world of strange powers and events (a call to adventure). (2) If the hero accepts the call to enter this strange world, the hero must face tasks and trials (a road of trials), and may have to face these trials alone, or may have assistance. At its most intense, the hero must survive a severe challenge, often with help earned along the journey. (3) If the hero survives, the hero may achieve a great gift (the goal or “boon”), which often results in the discovery of important self-knowledge. (4) The hero must then decide whether to return with this boon (the return to the ordinary world), often facing challenges on the return journey. (5) If the hero is successful in returning, the boon or gift may be used to improve the world (the application of the boon).
