Denise asked:
"The reason that I am writing is that I wonder if you can recommend some additional resources that discuss the relationship between the tarot and what you refer to as "The Proto Tree of Life." Your book is the only one that I have found that correlates the Tarot and its symbolism to the Mother-Double-Elemental relationship of the Sefer Yetzirah. I am very interested in creating my own Kabbalah or Tarot deck. Though I realize that much work has been done in this regard by the Golden Dawn and others, the Mother-Double-Elemental arrangement of the letters makes much more sense to me, and this is the reason why I've devoted much of my research to the traditional sources. If there are no other books relating to this, I'd appreciate it if you could point out which sections in your books I should pay most attention to when working on my own deck of cards."
David Allen Hulse answered:
"My prototype Tree is at variance with other traditional sources, for the attribution of the simple letters that cross the abyss are often given different attributes. I corrected the surviving proto tree diagrams to create the one appearing in the second key of the Eastern Mysteries. However, no work on the Tarot in English works with this tree. You will find however that there are a few traditional books on the Jewish Qabalah that do not address the Tarot, but do deal with this proto tree. If you are going to work out your own correspondences for such a Tree, use the Sepher Yetzirah attributes I give in the second key, and also use the Golden Dawn Hebrew-Tarot equivalents found in twelfth key. Combining these two traditions will give you the richest source of symbolism."
