I am not sure the connection between complex souls and desperate hopes for the next world. What's the context because it could likely mean so many things.
I think it's alluding to unhappiness from sensory overload, and the wish for something different or perceived to be better in the next life.
Aaah, I see. Yea, there are no wishes for something different or better. In my mind it just is. Whatever differences that might come are not going to be any better or worse, unless I've missed something somewhere. To me its about just experiencing according to what we wish to experience and being born with situations set up for such experiences to come about. How we take them once we are here will depend greatly on the hitchy glitchy, health and environment related stuff the body we are born to might have. After all, what is a physically solid human existence without the physical stimuli we encounter?.
