Setting the ultimate teleological vision for a lifelong mastery path, a philosophical community, or a narrative arc about human transformation. ---

If you govern yourself by intelligence, then when you leave the physical body behind and rise into the free upper air, you will be an immortal, undying god, no longer subject to mortal rebirth. The final two hexameters of the Greek text (p. 120) deliver the ultimate soteriological promise of the Pythagorean brotherhood: *Ēn d' apoleipsas sōma es aither' eleutheron elthēis, / Esseai athanatos theos, ambrotos, ouk eti thnētos* ("And if, having left the body behind, you come into the free *aithēr*, you shall be an immortal god, incorruptible, no longer mortal"). In archaic and Hellenistic Pythagorean cosmology, the sub-lunary atmosphere (*aēr*) is dense, turbulent, and the realm of *palingenesia* (the cycle of reincarnation into mortal bodies). Above the moon lies the *eleutheros aithēr*—the "free/unbound Ether," the luminous, pure upper fire where the stars and Immortal Gods dwell. By harmonizing the soul through the three stages of *Paraskeuē*, *Katharsis*, and *Teleiotēs*, the initiate breaks the wheel of rebirth, sheds the mortal tunic at death, and returns by natural buoyancy to the celestial *aithēr* as an autonomous divine intelligence. [INTERPRETATION: PRISCA THEOLOGIA / ESOTERIC] This closing promise of deification (*apotheōsis* or *theōsis*) echoed thunderously through the *prisca theologia*. Ficino, Pico, and Cornelius Agrippa cited these exact lines alongside the *Corpus Hermeticum* ("this is the blessed end for those who have attained gnosis: to become God") and the Psalms ("Ye are gods"). In the Renaissance synthesis, the "radiant Ether" is the empyrean or celestial realm into which the purified *ochēma* (starry vehicle) ascends once freed from elemental lead. For Ficino, Pythagoras was teaching the immortal destiny of the rational soul: through moral purification and intellectual contemplation of the divine Tetrad, humanity fulfills its cosmic vocation by rejoining the choir of the Immortals.
