Simultaneity, regarding the OIC's origins

[Aion]

I guess that depends entirely on how you are conceptualizing existence. Sure, you could refer to a primordial plenum as the fundamental 'container' of all existence, but I don't think that is the beginning or the core, I think that would equate to the emergence of intelligent infinity.

I view the Void as Mystery. This isn't to say it is not knowable, but rather I believe the closest we can come to know it is by touching our sense of mystery.

It doesn't make sense to me to say the Void or the primordial state 'is' anything, because I don't believe it is anything. I think the primordial state is void, empty, simultaneously nothing and everything in perfect equilibrium. Creation happened when, for whatever reason, this Void went out of perfect equilibrium, thereby producing all distortions.

In terms of the Ra Material, the 'reason' given for the One Infinite to invest in a finite Creation is so that it may fully know itself.

That raises many questions to me, such as why would the One Infinite lack anything at all?

This is a very prominent issue in Kabbalah too in that even though there is the tzimtzum, the reason for the Ain Soph Aur to contract in to Creation is still very mysterious.

Also, when I said "it just is", I wasn't referring to the activity or idea of 'one being', but rather suggest that it is even before beingness.
