Independently of the four symbols, each individual learns to recognize and describe things within the course of his/her life. Each person in their own way. In INDIVIDUUM® Universal, we call these perceptions Perception cards. There are 22 Perception cards, numbered from 0-21. These cards are used in tarot and oracle fortune-telling, and correspond to the Major Arcana cards in classic tarot. See the introduction RIDER-WAITE tarot – INDIVIDUUM® Universal.
