Would you be interested in books on Spirituality & Metaphysical.

As a newbie on here, I'm just doing a bit of research. I sell mainly books and am trying to determine what subjects are likely to be of interest to other eBid users. So as per the title, is there any interest in reading matter on this subject? Any advice will be greatly appreciated.

If the exercise I'm doing is against eBid regulations, would someone please let me know. If it's ok I intend to put a similar post in other subject threads.
