“Gnosticism” is the label scholars use for a body of teachings derived from the Mystery Schools of pre-Christian antiquity. Gnostics who protested against Christian doctrines such as divine retribution and Christ’s resurrection found themselves targeted as heretics and were brutally suppressed by early converts to the One True Faith.

Gnosis (“inner knowing”) was a path of experimental mysticism in which the initiates of the Mystery Schools explored the psyche and the cosmos at large. Using psychoactive plants, yoga, and sex magic, these ancient seers experienced altered states and developed siddhis, occult skills such as clairaudience and remote viewing.

Gnosis was a kind of yogic noetic science melded with parapsychology. In heightened perception, Gnostics developed a vast cosmological vision centered in a female deity, the Divine Sophia. The Gnostic creation myth is unique in that it includes a full-blown explanation of how inorganic alien beings came to be present in our solar system.

The Nag Hammadi material contains reports of visionary experiences of the initiates, including first-hand encounters with inorganic beings called Archons.

Archons inhabit the solar system, the extraterrestrial realm as such, but they can intrude on Earth.

This is exactly what Gnostics said about the Archons: they can affect our minds by subliminal conditioning techniques.

Their main tactics are mental error (intellectual virus, or false ideology, especially religious doctrines) and simulation. Archons are predatory, unlike a wide range of non-human and other-dimensional beings also know to the Gnostics, beings who are benevolent or neutral toward humanity.

Two types are clearly identified:

a neonate or embryonic type
a draconic or reptilian type

Obviously, these descriptions fit the Greys and Reptilians of contemporary reports to a T. Or I should say, to an ET.
