It's a little off tangent from the principle of the golden ratio, you are assuming that, because the golden ratio repeats itself and can be found almost everywhere (which is logical), it must be true for everything and not only apply it to reality as we understand it, but also to how you think it to be, in a way that the golden ratio specifically represents creation itself?
I understand where your reasoning is coming from now, but I don't need to know about the golden ratio to know that my perceptive abilities have limitations and that what we see and understand at any one point of time is but a mere fraction of the universe. I also fully expect there could be golden ratio's to be found all over this process if you look hard enough, but this fact in no way justifies that line of reasoning. I fail to see how the golden ratio has in fact any significance in this all, I'll come to my reasoning later.
I think you'd be better off by addressing your thoughts while staying fully submerged in the philosophical and symbolism, than basing it entirely on a scientific fundament. The risk you are taking by using things such as the golden ratio as part of symbolism is that you essentially seem to be wanting to rationalize your own way of thinking by bridging it to science. Whilest in fact your way of thinking does not need to be rationalized at all.
Buddha said it quite eloquently: "In the sky, there is no distinction of east and west; people create distinctions out of their own minds and then believe them to be true."
From a philosophical point of view, you mention the big picture, I can do big picture philosophy so here goes.

Depending on your stance on religion, this could be nature, God's plan, or if you will, the Golden Ratio (or the Golden Ratio as a fundamental part of nature).
But just as the golden ratio is part of the sum of the universe, so is the number 1 to the golden ratio. And the number 1 is just a concept of math us humans have defined. Sure, even that is part of the sum of the universe. But by that reasoning everything is. So what, specifically, is the significance of the Golden Ratio in it all? Only two things could be true. There either is no significance, or its significance is equal to all other things. I'm an optimist so I tend to lean toward the latter (neither could be branded as being wrong and both could be true at the same time.), but it's a mere matter of perspective. But in no way does the golden ratio hold more significance than anything else.
So is this a discussion about the Golden Ratio and it's specific significance, or is it about the sum of the universe or macrocosm as you put it?
I think you say one thing, but mean the latter. You mention the golden ratio and how much you love it, but mean the universe and how much you love that. Am I wrong? I don't think I'm wrong.
