Tarot reading is the practice of divining wisdom and guidance through a specific spread or layout of Tarot cards. Tarot do not simply tell your fortune, but also provide insight into the innermost truths of your higher self. In other words, the Tarot provide an evolved awareness of what you already know deep within.
Tarot decks have 78 cards (22 Major Arcana and 56 Minor Arcana cards), each of which provides detailed insight into a specific situation.
Oracle decks are a tool of self-reflection to add to your magical and spiritual practice, or just to use for fun. And while Oracle cards can offer insight similar to tarot cards, there are some major differences. There is no one way to make an oracle deck, the cards may contain messages from goddesses, famous literary witches, self-care tips or teachings.
Oracle decks can contain as many cards as the creator wants.
