I confess that I haven't been able to bring myself to give these romantic novels a try, though I get the idea of them having indeed a place and a function within our current lives, though I'm not really sure whether my conceptualization of their value is off the mark or not. To me, any fiction literature in general, whether it is romantic, fantasy, horror, science fiction, or any other genre, is a powerful tool for developing certain abilities that will eventually enable us to "transcend" our current limited 3D reality. Possibly, the two main tools to achieve this goal are:
Creative Imagination: our now somewhat dormant capacity to create realities and inhabit them, presumably put in abeyance through interference but maybe also through our personal decision to give preeminence to the Ego sphere. Once the skill is sharpened to a high degree we will presumably get to a level of expertise where we are able to flesh out the image-prompts supplied by the novel (landscapes, characters, events) to such a "realistic" level that they become totally immersive and as legitimate as any other reality. At this point we may be able to reclaim our status of co-creators.
Empathy: forget the all-consuming, ego-centered personal concerns and plunge into the reality of others to the point where we can feel as they feel and we can indeed "merge" with them for a while. This would be a sort of "drill" or practice-run to develop the abilities that will eventually enable us to merge with our multidimensional selves.
That said, I think though you could just as well become a powerful creator of realities with the Creative Imagination tool alone, but developing the Empathy side of the equation will possibly enable us to align with more desirable STO realities.
It goes without saying that literature, whether printed or in audio-book format, is particularly useful to acquire and develop this Creative Imagination tool, whereas movies and TV in contrast, in my opinion, can very well stifle it.
If you read Laura's intro post, though, you'll see that these books are very particular and not 'just any fiction'. They activate the sexual centre and the emotional centre specifically, leading to the release and healing of all kinds of karmic wounds, as evidenced by all the testimony in the thread. I've never before had quite the depth of experience and understanding of human relationships as can be had by reading these books. So I'd say that yes, without simply just trying them out, your conceptualization of their value is off the mark.
