G*D is Eternal Infinite, does not exist in any tangible way.
One cannot say about G-d that He is an existence, because then He would need a cause that brought Him into existence. So G-d, basically is a non-entity. He's responsible for everything else existing, but He Himself cannot be called an existence. Existence is just one of those great ideas He came up with one day.
Hey, next time you're in an argument with an atheist, tell him for me, "Yeah, we also believe that G-d is not an existence." That'll send 'em reeling.
As for all these descriptions of kindness, wisdom, etc you can't say that He isn't kind, right? Or that He isn't wise. Or that He doesn't have any particular quality. If He is infinite, He must have all of that, as well. That's called negative theology and a lot of philosophers, including Muslims and Christians, really got off on that idea. (For one thing, it answered that prickly issue of the big rock that even You-Know-Who can't lift.)
So back to our question, if G-d, the Ein Sof or whatever we will call Him, has no descriptors and can't even be called an existence, then in what way is He/It any different than nothing at all?
Let's talk in terms of information: Nothing contains no information. Yes, you can read that two ways. Let's try again: Whatever you say about nothing just isn't true. That's basically what nothing is: A vacuum of information.
The Ein Sof, on the other hand, can provide you with oodles of information. In fact, infinite information. Like what? Like the fact that existence extends from it. And it extends through the medium of ten sefirot, four worlds and all that engineering stuff. Really all the information there is and ever could be. The caveat is that none of that information tells you anything about the Ein Sof.
So we have three, not two, categories:
Something provides a limited set of information, which accumulatively describes that something.
The Ein Sof provides unlimited information, which accumulatively gets you nowhere. It's information. It's information about the Ein Sof. But it never gets around to telling you what the Ein Sof is.
Get this: All of reality is nothing but G-d's fingerprint. A fingerprint is information. It's a unique identifier that extends from one individual alone to point to only one place and tell you whodunit. But it tells you nothing about this person whodunit. Zilch. Just like any of those numbers they use to identify you in some privacy-intruding database: A number that points uniquely to you and only you, but says absolutely nothing about you (even if those bureaucrats believe that number is you). So the entire universe and all the higher ones, too, all the way up to the very first emanation, they all point to a single, ultimate Source of All Being--and tell you absolutely zilch about what that Whatever-It-Is is.
Ein Sof is not a three-letter but a four-letter one, translated into modern-think as "That Which Causes Being."
So is G-d Wisdom? Or Compassion? Or Love? Of course not. He is the Ein Sof, infinitely beyond any description. But if you want to find Him, you will study His wisdom, pray for His compassion and learn to love as He loves.
