For me, there is no tomorrow. It is not that sun will not rise it is just that rising of the sun is insignificant. It is not important as there is nothing to do.
There are no to-do lists to complete. There are no desires to fulfill. No story to be a part of. Tomorrow would have been significant for me if there were desires, to-do lists and stories. But after enlightenment, none is important. Thus tomorrow is insignificant. It would not matter even if the sun does not rise.
