The most complex mysticism praxis with the most complex language that I know of is the theoretical Cabala: "a technique for exercizing reason or, instructions for use of the human intellect... it is said, that angels gave the Cabala to Adam after being expelled from the Garden of Eden as a means whereby to return there" (Wolff). The 10 Sephiroth with their 22 connecting pathways constitute a sheer inexhaustible, network-like reservoir of associations, connections, punctuations; its construction principle is binary and it is built of the basic tensions of theoretical reason (CHOCKMAH) and the power to concretize, to form (BINAH). The only meaningful mode in which the Cabala can be read and re-revealed over and over again is that of interpretation. In this, the Cabala and art are akin.
