The Kabbalah Cube of Space:
The 22 hebrew letters can be arranged in a kabbalistic system of space. Every letter describes a particular direction, which direves from the 7 major directions in space: north, south, west, east, above, below and the centre. These 7 main directions are at the same time the 7 double-letters, double for they can be pronounced in two ways.
The 12 sides and 3 middle axes of the Cube of Space, are the connections of the 7 main directions. In the kabbalistic book called the Sefer Yetzirah, the book of creation, all directions are direved from the 32 hidden pathways of wisdom.
