The Devachan is the world of the spir­i­tu­al arche­types, the arche­typ­al world. In the Jew­ish Kab­bal­ah it is called Atzi­luth or Azi­lut (Hebrew: אֲצִילוּת “nobil­i­ty, sub­lim­i­ty, good­ness, fire”) and com­pris­es the high­est tri­ad of the Sephi­roth, name­ly Keter (crown), Chokhmah (wis­dom) and Binah (intel­lect).
This world does not pri­mar­i­ly reveal itself to spir­i­tu­al per­cep­tion in inner images, in imag­i­na­tions, but through inspi­ra­tion as a har­mo­ny of spheres expe­ri­enced by the “inner ear” as sound, which is also reflect­ed in the effects of the sound ether and in the numer­i­cal rela­tion­ships in chem­i­cal reac­tions, and then fur­ther as the word expe­ri­enced inwardly.
