Nothing, because we almost certainly don’t live in a consensus reality.
Focusing is a mind and memory skill.
Didn’t you ask this last month?
No that was the other guy.
Everything disappears. What remains is that I am the universe, as are you, as are my cats, and everyone else, all alike, all a version of each other, all one, all with just a momentary lifetime of consciousness, some lucky not being bombed. But most live it being consumed by the dance of work & money & religion & relationships & fashion & pop culture & all of the social dogmas like any of that is what life is all about. When I focus & connect with my humanity, I see that none of it is real, all of it is made up, socially agreed upon, maybe even legally encoded depending on situation. The only thing real is here & now. And what we truly yearn is each other’s company, ie. to ‘connect with the universe’.
Everything except the boobs.
