Die Vertreibung aus dem Paradies ist in ihrem Hauptteil ewig: Es ist also zwar die Vertreibung aus dem Paradies endgültig, das Leben in der Welt unausweichlich, die Ewigkeit des Vorganges aber (oder zeitlich ausgedrückt: die ewige Wiederholung des Vorgangs) macht es trotzdem möglich, daß wir nicht nur dauernd im Paradiese bleiben könnten, sondern tatsächlich dort dauernd sind, gleichgültig ob wir es hier wissen oder nicht.
Expulsion from Paradise is in its main aspect eternal: that is to say, although expulsion from Paradise is final, and life in the world unavoidable, the eternity of the process (or, expressed in temporal terms, the eternal repetition of the process) nevertheless makes it possible not only that we might remain in Paradise permanently, but that we may in fact be there permanently, no matter whether we know it here or not. [Kaiser/Wilkins]
The Expulsion from Paradise is eternal in its principal aspect: this makes it irrevocable, and our living in this world inevitable, but the eternal nature of the process has the effect that not only could we remain forever in Paradise, but that we are currently there, whether we know it or not. [Hofmann]
I don't know, but I guess that number sixty-four ends at the colon, and number sixty-five is the expansion after it.
If paradise as a condition is eternal, and therefore outside ordinary clock time, then to be there once is to be there always. So there is eternal presence in paradise, and eternal expulsion from Paradise. In that case, the question would not be how to find the way back, but how to realize the extent to which you are still there.
To be in paradise without knowing it is not expulsion, and if that is possible, then it shows paradise is not only a state of mind. Paradise might be defined as an eternal place you get expelled from. The door is open and the man doesn't go through; in this case, you are in paradise but you must leave, forever be leaving it. This is like the inverse of the castle, isn't it? Or is it that the way to belong to the castle is to try to get inside it, without success?
