"The Spinal Column is considered the trunk of the Tree of Life in Kabbalah and its subsequent pathway’s or the energy nadi’s of the body are considered the branches. The lower part of the Tree, near the genital organs, leads one to the underworld of sexual lusts and depravity and this place brings about spiritual death within the lands known as Hell or the worlds of the klipot. The upper branches of the Tree of Life lead one to the Heavens above in the mind and beyond and these realms lead to spiritual life, back to the Garden of Eden.
There are 33 degrees of the spinal column, or the Tree Trunk, which must be climbed with the Sacred Seed of Alchemy and each ‘step’ or each ‘degree’ leads to higher states of illumination.”
