does not directly mention a "cube of space", nor any kind of cube. Case based the Cube of Space upon two verses in the : the first, in chapter 4, associates six Hebrew letters with six cardinal directions (up, down, east, west, north, south); the second, in chapter 5, associates 12 Hebrew letters with 12 diagonal directional arms or boundaries (different translations use different terms), which Case interpreted as the 12 edges of a cube. Case associated his Cube of Space with the Tree of Life of (). He based that association upon paragraph 95 of the . That paragraph does mention a tree, though does not specifically name it the Tree of Life; it states that a tree is inside the twelve diagonals that are mentioned in the Sepher Yetzirah. Because the Tree of Life consists of 10 , Case associated the three "mother" letters (, , ) and seven "double" letters of the with ten corresponding . Until the publication of Case's The Tarot, most English-speaking occultists had never heard of Case's Cube of Space concept, nor any alleged correspondences between tarot and the Tree of Life diagram, though the latter correspondence have become common in modern times (e.g., many tarot decks feature a Tree of Life diagram on the jacket of the Fool). Until the mid-1990s, there were almost no other books in print which even mentioned the Cube of Space. The ones that do (sometimes in different terms such as "the Qabalistic Cube") defer to Case's writings on the subject.
