Well of course your brain is keeping a certain state, even while in complete meditation. So what is the point? It is not like reaching a certain meditative state would make you superior among others, or a super-human even. Many have suggested that people reaching such states eventually do return back, and for some, such states even dissipate eventually if they don't keep up with the practice. Ultimately, the idea is that the state of 'here-now' (whether arrived through practice, observation or heck even induced through means of substance - though there are differences) is the state when You are not your mind anymore. So in that sense, looking at above suggestion about memory, I would simply ask: what is the need of a memory?
