Among 9 jhanas which is deep sleep? Please provide suttas
I plan to do a meditation until I can achieve the same experience as my deep sleep but I don't know whether it's the first jhana or even cessation of feeling and perception or even nibbana hence my question
After that kind of meditation I won't sleep forever because I think that meditation is enough that meditation itself is deep sleep
I am inspired by dipa ma who did meditation for 2 days non stop and buddha Siddhartha(7 weeks non stop)
I think my meditation should be more sublime than my deep sleep if it's not then it's a shame it just doesn't make sense that my deep sleep gives me more peace than my meditation
Because bhikku thanissaro states that even during 4 rupa jhanas you can still hear sound while during my deep sleep I can't hear any sound I assume the deep sleep experience can be attained after the 4th jhana but I am not sure which
I think it's not cessation of feeling stage either because during cessation your upper brain won't function (flat zero brainwave) while deep sleep still gives you delta brainwave but I am not sure
Thanks 
May you all be happy my friends,
Sorry for my bad english I am still learning friends
I've got a simple answer for you: Sleep is not a jhāna. The Buddha never says, not in Pāli not in Chinese not in Sanskrit, that sleep is a jhāna. Sleep is also not nibbāna. Sleep is also not nirodha. You just forget your dreams when you wake up and it seems like you were up to &quot;nothing,&quot; but your mind was quite active despite you not remembering it.
