Tarot itself is a fascinating field; unfortunately, many books written about it are appallingly simplistic, uninformed, and simply not helpful. This particular tome of folly was the first book on tarot I ever bought--it left a sour taste in my mind that drove me away from a blameless field for some years.
The "lessons" presented are absurd--pressing an unknown card to your "third eye" and solar plexus to attune oneself to the "energy" of the card; staring blankly at the card to "meditate" upon its meaning, etc. All of which is well and good, I suppose, if you happen to be "psychic." Call me a cynic, but most people simply aren't; drivel like this will either drive them away or, worse, simply confuse them. "I'm not feeling any energies! I must be doing something wrong!" Well, no, you aren't.
Connolly touches on links with Kabbalah--in a painfully uninformed manner. Readers who already *know*, even to a trivial degree, the historical development of Kabbalistic philosophy and symbolism, will feel their gorge rise. This is the kind of work that insults entire fields. Tarot is a rich ocean of symbolism that has evolved over the course of centuries--this reduces it to a shallow pond. And that's the worst part of all--books like this can catch people unawares, teach them that wading in muddy ankle-deep water is equal to swimming. It's not. Avoid this one.
