THE IMMORTAL KABBALAH
We have seen that there is a direct correspondence between the four Hebrew letters k, b, l, and h that constitute the word kabbalah and the four Sanskrit consonants ka, ba, la, and ha representing the first, twenty-third, twenty-eighth, and thirty-third layers of the metaphysical Logos.
Yet because the letter h stands as the final letter of the word, it also has an interpretation as aha, the sound into which the consonant ha is transformed when it stands at the end of a word or sequence of letters.Whereas the initial sound ha denotes the shore of this world (the thirty-third layer), the final sound aha denotes the shore of the other world (the fortieth layer). In this sense, the word KBLH may be viewed as a sonic formula that encodes the immortal wisdom extending beyond the first thirty-three layers all the way to the fortieth layer.
In the tradition of kabbalah, these forty layers (or sephirothic emanations) were viewed as organized into four sets of ten and were conceived as the four worlds denoted by the Atziluth, Briah, Yetzirah, and Assiah. The lowest of the four worlds, Assiah, was viewed as the most concrete and physical, and the highest of the four, Atziluth, was viewed as the most abstract and archetypal. The ten layers that make up the Atziluth extend from the thirty-first to the fortieth layers. This was known as the world of spiritual archetypes, and the highest of these layers (the fortieth in the ascending direction) was known as the Great Sacred Seal, the immortal archetype from which are copied all the inferior worlds (upheld by the other thirty-nine layers). The knowledge pertaining to this immortal archetype, however, goes beyond the cosmic wisdom; it is part of the immortal wisdom, which deals with the infinite and immortal realms that lie beyond the outermost shell of the cosmic egg.
