My first post got eaten by the Internet monster good thing too.
Was having some problems with your use of the term abyss as it resonates for me with the term abysmal. But in the interim my brain has reframed it.
I remembered the beautiful film The Abyss (which makes gan's choice a really great one) and went looking for my favourite clip of it when the heroine comes into contact with a fragile beautiful sea creature who is trying to communicate. And it struck me, supposing these are not really three individual choices but three facets of the same one?
Suppose Gan does not have to choose at all? She could do all three?
The Abyss then stands for: A. The search for the sea creature aspect of self B. The reach to communicate C. The journey to renew
The film also more apt as it is about repairing an M. This is the amazing clip of the first encounter:
The image I was originally reaching for was the valley obscured by clouds a French film , one of the most beautiful films ever made although it is about an affair and fascination with an OM. I thought gan might like the link any way, it is about New Guinea. As I know you are a traveller and far too young to have been around to see the original.
