To put it in object-oriented terms: I am my mind and my body. Think of inheritance here: I am my mind, and I am my body. Because my mind is conscious, it's fine to say that I am conscious.
But the universe is more like a container (a set, say). It isn't its contents, it merely has them. So while I am part of the universe, and I am conscious, that doesn't mean that the universe is conscious. Instead, it contains consciousness.
> Brahman is also conscious, because universe is conscious, and the universe is a part of Brahman.
Objection, your honor. Assumes facts not in evidence.
And: I'm not Hindu either, but I'm not sure, within Hinduism, whether Brahman is conscious.
So the only explanation I can understand where you can be separate from the universe is, if you weren't a content of this universe and I'm speaking to a super-natural being.
Otherwise, if you aren't supernatural, then all of you is a part of the universe, and that makes the universe at least as conscious as you are.'
The only reach from universe to Brahman, is whether there are multiple universes, or is this the only one.
In my opinion, all positions besides Pantheism or Panentheism are illogical.
The universe is conscious, because you are conscious, you are a part of the universe.
Brahman is also conscious, because universe is conscious, and the universe is a part of Brahman.
I'm not Hindu, but this is pretty conclusive proof.
