This investigation into the world of patterns is leading to spirituality. This pattern represents the 'Sephirot'. It looks very similar to the central structure of E8.
The idea of the ten Sephirot (literally the "categories" or "symbols") is the most familiar and widespread of all Kabbalistic motifs. It first appears in the books of Sefer Yetzirah and Sefer Bahir, and probably dates from the first millennium. It is a very conscious attempt to offer an alternative to a rational, philosophical view of how God interacts with humans and vice versa.
In a nutshell, the Sephirot are like a transistor that enables us to receive messages and send them. If God, Ein Sof, is not physical in any way, then there is a problem as to how there can be any interaction between the purely spiritual and the material. By interposing the Sephirot they become the channels through which we receive and transmit the lines of communication with the Divine.
