Osiris and Set - Mental Balance 

Duality, in the world, and the mind is essential to stability. Balance can not be had unless there are 2 sides to the scale. In Egyptian and the Hermetic esoteric tradition, contesting sides creating equilibrium, is a core logic. Opposing forces of day/night, dry/wet and birth/death are examples of physical balance the Earth requires. Without them, it would not be able to sustain life, or be as it is know to us today. Gazing into the mind, one can see the parallels. For instance, the mind must become balanced for spiritual progression. One must learn to walk a centered path, and come to a point where the Divine is proportioned with ones soul and sense of body. Until this is part of are persons life, they will not have what is required to sustain a spiritual life in the mind and body, or progress spiritually past a certain point.

There are so many facets of the mind, such as male/female, logic, conscious/subconscious, the hunger for that of the physical, making each persons journey for equipoise unique.

  Set battling Horus the son of Osiris

The Egyptians used the "Myth" of Osiris's battle with Set/Typhon as an example, or archetype, of this Gnosis of Balance through duality. Also, Horus's battle with Set served a similar purpose.
