The Major Arcana tarot cards are the first 22 cards in a tarot deck. They represent the cycle of life. When you receive a Major Arcana card in a reading it represents the big overarching changes that are happening in your life.
Each of the Majors show us a stage of life where we are at, or what is to come if we continue on the current path. We do have the ability to change our path with every decision that we make, but in order to grow spirituality, we need to experience each of the cards at some point in our souls journey.
