Q: Is tarot witchcraft? Does it tell the future? Is it... devilish?
A: Reading tarot cards is a tool that can be used many ways. Tarot here is a tool of self awareness and reflection. In my opinion, reading the tarot does not tell my future (or call upon any divine forces), but uses imagery and archetypes to give me insights and new considerations to my current experiences.
Q: Can I play Gardens & Griffins without a tarot deck?
A: Yes! You can use a standard deck of cards and an online resource to interpret meanings. I like the chart
here. Alternatively, you can use an oracle deck, or even
make your own oracle deck.
Q: Am I literally feeding the griffin "change," "abundance," "temptation" ?
A: The tarot card meanings are a jumping off point for your imagination. Let yourself be soft and loose handed with interpretation and associations. The griffin might be a metaphor for anything you are trying to nurture.
