The Cross-Section of the Queen's Chamber in the Pyramid Forms the Sigil of Lucifer

[Infinite]

Wait, so eating the apple of knowledge caused the veil of forgetting metaphorically?
I thought it would open their eyes.

The "tree of the knowledge of good and evil" means the choice between service to others and service to self. Remember Ra spoke that STS possibility of choice was implemented later in the Creation, with the intention of extend the free will.

What's interesting is that Ra offered this particular analogy on their own without the group making any reference to Lucifer. The only other time it shows up in the material is a later session, 84, when Don says "Lucifer or the Devil" in reference to the Tarot card. Thus, it strikes that Ra clearly already thinks about Lucifer in a particular way.

I see Lucifer as one of those Logoi which implemented the STS possibility of choice. The reason of this Logos have been called of "angel" or "archangel" and the context of war in heaven, are due the Jewish Christian culture where the concept was disseminated.
