The Major Arcana are the greatest Archetypes, the greatest secrets behind what is, and the energies that create everything that happens. They are like enigmas that man has to solve within himself and also an inner journey from one state to another to manifest his destiny.
The minor Arcana are related to the four main suits (Wands, Swords, Cups and Pentacles), which represent the different levels of existence and the various levels within us: the spiritual, mental, emotional and physical worlds. They talk about the way we relate to things and the way, on each level, we manifest what we believe.
