Basically different people have different opinions, and Echols is saying that it’s, and I quote from te lined vide at 1:03 above: “NOT union with the divine”. He equate it with the "god of th old testament…
So i was wrong he is claiming it’s the Jehova entity that was a war god of a desert tribe that is te one and only HGA and we don’t all have our own.
I don’t really see why that’s useful though, as I have so little respect or sense of power from that being from personal experience, so this doesn’t add up in my mind to explain how people find this to be a powerful practice, unless, they were all really only access their own personal power all along, which is possible imo.
He quotes Crowley who is saying pretty much that HGA is Source as far as I can tell… and then immediately contradicts him while claiming he (Crowley) is saying something I really think he isn’t.
Echols Quoting Crowley in “Magick in Theory and Practice”:
"He’s tells you exactly what “attaining the knowledge and conversation of the HGA” … [and] … “marriage of the HGA”:
Crowley: "There is a single main definition of the object of all magickal ritual. It is the uniting of the microcosm with the macrocosm. The supreme and complete ritual is therefore the invocation of the holy guardian angel."
Well, we can see fairly obviously that invoking a desert war deity isn’t going to do that. It is not “The macrocosm” by definition.
I don’t disagree that mystically the object of enlightenment is union with the divine/Tao/Source/All/macrocosm, if you can use all these terms for that.
I DO strongly disagree with Crowley that this is “the object” of all rituals. Because energy working achieves magick via ritual (or not,) and this is a tool that does not require his level of union. Neither do I think most mages achieve this union most of the time during ritual. Having Siddhis might. You might as well say using any tool is union with the divine, why not? My Black & Decker drill will be thrilled to hear that. 
I would also notice another problem here, in attempting to find agreement with someone who is basing his opinion off what I think is a misunderstanding of another person who I also disagree with, all I get out of this is, these people are all really confused.
They’re working themselves into knots of semantics and assumptions, until the models are more important to them than understanding the underlying truth and finding a personal way to explain it, and I find that pointless and unhelpful, so I think I’ll just go figure it out for myself. I have my own ideas that are more in line with Taoism, but this isn’t how I’d describe it.
TL;DR, you are correct that Echols is saying Crowley’s HGA is the deified personality knows as the desert troll god Yahweh/Jehova.
Ditto.
