Employing a practical, mathematical approach, author Kenneth Coombs presents a scientific and comprehensive analysis of the twenty-two Tarot cards in the Major Arcana. This detailed examination deciphers the reactions and interactions of the Tarot cards with each other, rather than simply the individual meanings of each card. He shares the results of the 231 possible combinations.

In Tarot Alchemy, Coombs, a chemist with more than thirty years of Tarot card reading experience, discusses a novel approach to understanding Tarot. He details the process of alchemy, which involves looking at each Tarot card as an element. The interactions of the Tarot cards are like reactions that create molecules, and it is the interactions of the Tarot cards with each other that give depth and enlightenment in a Tarot reading. This process has given him the ability to determine specific timeframes and even names of people and places using the cards.

His approach of deciphering the interactions in a scientific way leads to new insights about the meanings of the Tarot cards in a reading. Tarot Alchemy shows how learning to find patterns in the cards strengthens intuitive abilities and unlocks the doors to understanding the Tarot cards.
