Hi Dhabba,
Thanks.
Sariputta says he entered into concentration – so there had to be some consciousness, as even he said was perceiving, is all I’m saying.
The only state I’m aware off in the suttas in which consciousness (hence any perception) is utterly absent is with saññāvedayitanirodha and those rare beings who are labeled non-percipient.
Definitely, subtle stuff here and I’m not sure “where in existence” is an applicable question since what’;s being described is certainly beyond the five senses. Can we even apply “where” to the 1st jhana?
Also, as in the Bāhiya Sutta, Ud1.10:
"When you’re not ‘in that’, you won’t be in this world or the world beyond or between the two. "
Not being in these worlds can refer to not being stuck in this world, another world after rebirth, or in between death and re-birth.
This was said while Bāhiya was still alive and can apply in a similar way to Sariputta’s comments here.
Just saying…
