Fortune telling, also called divination, are a wide variety of practices. Divination can be defined many ways- for me, it is simply a way to understand and read signs in relation to a certain topic. Many, many forms of divination exist, from the very simple to the complex.
Many popular forms include oracle decks, dice, tea leaf and coffee ground reading, predictive astrology, tarot cards, and divining using rocks, crystals, and stones.
You can even create your own way of divination, as long as it aids YOU in unleashing your inner wisdom.
