Heavenly Adam. The synthesis of the Sephirothal Tree, or of all the Forces in Nature and their informing deific essence. In the diagrams, the Seventh of the lower Sephiroth, Sephira Malkhooth—the Kingdom of Harmony—represents the feet of the ideal Macrocosm, whose head reaches to the first manifested Head. This Heavenly Adam is the natura naturans, the abstract world, while the Adam of Earth (Humanity) is the natura naturata or the material universe. The former is the presence of Deity in its universal essence; the latter the manifestation of the intelligence of that essence. In the real Zohar not the fantastic and anthropomorphic caricature which we often find in the writings of Western Kabbalists—there is not a particle of the personal deity which we find so prominent in the dark cloaking of the Secret Wisdom known as the Mosaic Pentateuch.
