Those quotes are from the Buddha.
Sorry we haven’t apparently caught up. 
Not quite. Sorry if I was unclear. I was simply trying to convey that in the absence of five of the six senses, there is peace not through entering into another “thing” like nibbāna, but that the temporary absence of the hindrances and much sense experience in consciousness is an example or a taste of what it may be like to being free of them via cessation.
It’s not worth pushing this mere example too far.
You’re free to take this up with a number of Venerables who have much experience with jhanas.
That opinion is up to you.
But there’s consciousness, which is impermanent and dukkha.
No preference for unconscious states. Nibbāna is not a state and in final cessation conscious and unconscious do not apply any more than left hand and right hand.
The sleep example I used earlier was just that – a limited example to offer a point and was not an ontological position.
Well, I guess that settles the matter for us all!
