My Answer: It’s not long, since in reality – there is no time. Time is Reshimot creating this movie inside you.
Once you connect to everyone else, you will compress time so much that all actions will happen very quickly, one right after the other. You can either feel time like a star that exists for billions of years, or like a little bug that lives for just a few hours and dies; everything depends on your sensation of time.
We feel time only because our egoism switches on, stretching out time between actions, between Reshimot. If not for our egoism, Reshimot would externalize instantly, without any intervals, and would all be constrained into one point.
