My first reaction to you calling A&P was "nah". But I'll be better than that and instead say that
if this is A&P it is nothing like I thought it might be. Rather boring. Today (the next day) was pretty uneventful. I have to force myself to think if there was anything out of the ordinary. Slightly carefree. My mind feels a bit light as it hasn't been grabbing at so much today. Other than that: zilch.
I'm pretty sure what I experienced yesterday in my sit had more to do with samatha jhanas than with vipassana jhanas, but I have no expaination for the insane equanimity I experienced.
Thinking I'm enlightened is nothing new

but I agree that the combination is rather suspect, as you say.
