Interesting questions seem to revolve around the challenge of self and how (or if?) to frame it:

• No-Self — "... centered on no particular thing, but on all things ..." (Charlotte Joko Beck)
• One-Self — "... given responsibility, over time, so that it can reliably be there to take responsibility ...." (Daniel Dennett)
• All-Self — "... folded into the universe and participate in its unfolding ..." (Jon Kabat-Zinn)

... perhaps undefined, unanswerable challenges of free will, agency, worthiness, existence, awareness, attachment, identity — perhaps illuminated by thinking about the absence-or-presence of other "selves" — and perhaps worth thinking (and not-thinking?) about!
