What he says is not correct, even based on my personal experience. He got the hint, though, because what he says applies to arupa jhanas, which he probably mistakes for rupa jhanas, as it is true for arupa jhanas. For example, when I was going through arupa jhanas, they were the same experience, and the difference between them was only knowledge about their nature.
Imagine that you go into water, the initial experience is like the first arupa jhana but once you stay a while in that water you start noticing more things about the fluidity, how it feel and you experience more and more knowledge about nature of it thru that experience as you become more simmered but the experience per se does not change.
For me, all arupa jhanas are the same; the difference is only the depth of knowledge you get from them as time goes on.
My theory is that arupa jhanas are different “roads” of jhanas rather than rupa. Normally, you see that you need to go “one by one” from rupa to arupa. I think it is not true, as you can go directly to arupa, bypassing the first 4 rupa jhanas. Some sources I checked (later commentaries), like that you can go “really fast” that you are not aware of doing so, I can not confirm that because if things like that happened obviously I was not aware.
A guy in the video seems to be misinterpreting his own experience. That’s why I don’t like to talk about jhanas a lot, because some fake teachers may find this post and act like they have achieved something. In my long journey of meditation, I didn’t find anyone, I think, who actually attained jhanas and properly described them as the real thing. Only Abhaya Thero students explained their jhana properly. (rupa jhanas only though)
