I think it's really important to remember the reason for the season - whether you share the Christian faith or not. At the heart of Christianity are three words: love, peace and forgiveness. My thinking is that over indulging in any of these things is unlikely to result in stress, debt - or indigestion.
First up I need to be clear. I am a tarot lover, I have been reading the cards since I was 13. At first for friends, but now I do so professionally. I love and praise the genuine guidance tarot can offer, they are like an objective best friend. From my perspective tarot can help you figure out what you already, deep down, know. A good genuine reading should compliment your intuition about your own life. A healthy reading does not offer answers or prediction so much as it offers clarity and perspective.
The longer I live and explore a spiritual life the easier it gets. When I started off my adventures I visited a dozen or so different faiths and I got down and dirty with the meditation, the praying, the mantras. I had the patter and the pose, but none of it felt right. Some of it felt convoluted or ridiculous. Most of it didn't quite fit, it was someone else's story, someone else's journey.
