The world exist as a symbol of Brahman/Creator in a sense that it is put forth from It and doesnt have any separate existence from It. The world could be quite different just like symbols can be very different and since there are probably many different universes thats actually true but non of these universes exist separate from their Source.
So do you have any evidence of this? Any telltale objectively verifiable evidence of this Source? What more can we say about this Source so that we can more reliably look for evidence of its existence?
You seem to know little about Aurobindos life (or death) but I suggest you take little more trouble in that regard before you label someone a hypocrat.
Aww, but I felt like I was getting to know him so well from all your posts!

Seriously though, I've been down the Indian mystic road before. They're all essentially the same in what they say, how they say it, and how they think.
Well may be Reality can be unchanging yet transcendent at the same time. What if illusion itself is illusion so what appears to be a change cant be essentialy different from the "changed".
What if it isn't. Evidence please.
True, however if you realise any object not only in its objective appearence and functonality but in its essential reality - consciousness - it may open totaly new vistas and unlimited potential.
Evidence please.
Objective things arent an illusion but rather their objectivity is. Subjective things are bound to be form of consciousness in this light as well. The wider and profounder "the form consciousness" the more real it is.
You'll have to explain the first sentence to me, I don't follow. What do you mean by "wider" and "profounder", and why should these be indicators of realness?
Words like "consciousness", "cosmic" are impressively sounding to you yet very abstract and somewhat reassuring in the same time.
And apparently to "your self-consciousness" whoever said "I and my Father are one" was nothing but a colossal egoist.
Aurobindo needs impressive methaphysical vocabulary to form a compelling worldview and you need quick glance and your own self-knowledge to make decent judgment...
No they don't impress me, in fact their frequent and associated use (e.g. in Sri Aurobindo's writings) sets my BS radar off. They are clearly impressive and reassuring to people like you though.
I have no idea what "I and my Father are one" was supposed to mean, but I think it was some esoteric idea which has little to do with colossal egotism.
People like Aurobindo use an impressive metaphysical vocabulary to win over followers and disguise the fact that they're talking a bunch of hot air. Where you see an impressive world view, I see a big bunch of word salad.
