To take the perspective of being is to view experience in the frame of 'all possible experience', which is of course quite impossible. All possible culturally cognate human experience is already far too vast, and so is all possible experience that you might have were you to admit it. What you actually experience is such a tiny sliver of this, a speck of dust in a violent conflagration. But then to view it as special in the most general way possible, or sub specie aeternitatis, even that is impossible, but it is an active limit - unexperiencable but part of the essential structure of experience. As are all those other kinds of infinite extension. You must take account of the infinities in which you are already thrown.
