If the meditator wishes to attain the next jhana, they simply hang out in nothingness until they get bored with perception entirely and understand that even perception is somehow disconcerting. Thus, the mind will eventually shift on its own to the state with the perplexing but thoroughly appropriate title of “neither perception nor yet non-perception,” hereafter “the eighth jhana” for the sake of brevity.

This state is largely incomprehensible, but it is absolutely not emptiness. It is empty, but this is not the attainment of that understanding. The eighth jhana may very easily be confused as being emptiness, especially if it is attained through insight practices (remember that insight practices can simultaneously cultivate concentration and wisdom). There is no reasonable way to attempt to describe this state, save for that it is a mind state, and thus is not emptiness, as emptiness is not a mind state or anything else for that matter. I am tempted to say that one is simultaneously focused so narrowly that one notices nothing and yet so broadly that one doesn’t notice even that, but such a description doesn’t quite do this state justice. One way or the other, there is complete inattention to diversity. The eighth jhana is the highest of the ordinary states of concentration that can be attained, ignoring the attainment of the cessation of perception and feeling and a few other attainments mentioned there.

Non-dualism.
