Tarot and The Kabbalah
In the Tarot and The Kabbalah, the term ‘Arcana’ is plural. The singular aspect of this term is ‘Arcanum.’ ‘Arcanum’ refers to a type of knowledge, which is for the initiated, or a kind of knowledge that is mysterious for the average person. It is a science or understanding that one has to be introduced to. When we study the twenty-two Arcana, we are studying twenty-two laws, or twenty-two mysteries, that we have to be initiated into experientially in order to understand them.
