When you look at how Trimurti is oftentimes portrayed, you will see one person with three faces and six hands. That's, IMO, very apt depiction. That's also what I was alluding to when I said that where is Brahma, there is Shiva (and of course also Vishnu).

As for your question — I, honestly, didn't give it too much thought, but I always found the obvious similarities between Brahma and gnostic Demiurge rather striking. After all, both are creator gods (or means of creation) and have that problem that they don't recall being "created" thus consider themselves the root of all being. (Though Gnostics are not so benevolent toward Demiurge and IIRC consider him an usurper. By their mistake, I must add. Sadly, that mistake then informs their relationship with physical world in a rather unfortunate way.)

Here I must stress again that I view Trimurti and Demiurge as the primordial forces of nature that "rule" and shape the universe. And in line with Trimurti and Demiurge, many people consider them to be the be-all end-all of everything. So, I would say that that image of Elohim manifesting another agent as "performer" of creation is apt. I would only add that that manifestation cannot be temporary - that agent will fulfill its purpose until this universe ceases to be. Then the question is, which “level” it represents — fundamental forces, particles, atoms? Space-time dilatation before hot BB? And also, let’s not forget that even Elohim is already many-in-one exactly as Trimurti (that’s, AFAIK, where Gnostics got their Demiurge).

But as I said, I don’t bother much with these details, hence my scattered thoughts on the matter.
