Terrestrial Adam, the Earthly Adam, of whom Dr. Franz Hartmann wrote in The Secret Symbols of the Rosicrucians:
"THE TERRESTRIAL ADAM. - Adam after his “fall”; i.e., the original man having become the distorted image of God by having lost his original purity in consequence of disobedience to the law and desertion of the straight line of the universal divine will. This disobedience is illustrated by the allegory of the “eating of the apple in paradise”; the “snake” which tempted Adam and Eve is the illusion of self, causing man to imagine to be something different from the universal God, and thus creating within him personal desires."
The definition clarifies the state of general humanity in Dr. Hartmann's period, and remains still a predominant condition of the technological human into the twenty-first century. Additional information, however, may be gleaned through gematria as Terra Adamica sums to 86 in the Latin Cabala Simplex. The Hebrew word נבדל, nevedel, meaning 'different, divided, separated, set apart,' sums to 86, as does הטבע, ha-tevo, 'nature.' What sets mankind apart and separate from his creator is the pull of the primitive human’s animal nature, explained elsewhere (alchemically speaking) as Sulphurous action suppressing Mercury when acting upon Salt. The Bhagava-Gita expresses this condition by the action of Rajasguna acting upon Tamasguna to suppress Sattvaguna. The Salt principle, Tamasguna, predominant in all seven force centers in the etheric aura causes 'separated desires' to seek sensation in all its forms. The sensations can never be appeased, turning the whole life into 'lead,' weighted down to earthly conditions by insatiable, sulphurous desires.
The Latin, plumbum, totals 86. This is 'lead' the alchemical process affects to Gold. The 'Snake' in Genesis, alluded to above, reveals Dr. Hartmann's knowledge of subtle esoterica. The serpent, symbolic of Universal Desire, drives Universal Consciousness toward manifestation of tangible substance. Using the verb 'to imagine,' he intimates his knowledge concerning the spelling of 'serpent' as נחש, nachash, in Genesis to be the same as an ancient Semitic form for 'Copper,' the metal sacred to Venus. She is creative imagination, love and desire, personified as the goddess (See COPPER). Enmeshed by our false desires, we live as Terra Adamica, and Lead.
But these creative desires, focused on selfish pursuits, can once again liberate. אלהים, elohim, translated as 'God' in the first chapter of Genesis is more exactly the term, 'Divine Creativeness;' it also sums to 86. By purifying our base desires, as alchemists advise, we discover the desire nature inherent within our true Divine Self. Turning within for liberation, transmuting selfish desires, we come into union with the True Celestial Adam, whom Dr. Hartmann defines: “The divine man-forming power in its original state of purity as an image of the Creator.” Returning the King to His Throne, His imagination builds the super-human from Tiphareth.
