At the fag end of your logic, you will always find two options, but you will never be able to choose between the two no matter how much you try, this is the end of duality – you are able to observe two option from a third point – this third point is the point of non-duality or the third eye – you can see the two position but will never be able to choose between the two.
You have taken a jump from the two opposite positions to the third positions, now there is no going back.
At enlightenment, the possibilities come to and end, but how the possibilities have come to an end, I cannot say, but if you have arrived, you will be able to corroborate your experience by reading this post.
Possibilities come to an end under two circumstances:
(1) When the changes have happened, when the possibilities have been able to push existence enough and make the required changes in existence thus releasing the pressure – the dream has come true
(2) When the dream will never come true, hence there are no possibilities, the possibilities have not been able to change existence and hence have failed and like a balloon, has burst. The pressure has been completely depleted
You will never known which one has happened. You will never know why the possibilities have come to an end.
Now, there is no driving force to pursue the dream – it has either come true or will never come true. In either of the cases, there is nothing to do – hence no driving force.
If you are able to see both – you are sitting at the third point, a non-dual position thus able to see both the positions, but not able to chose either of them.
Sitting in this third position, you do not know which path is right. How what is the right path? The path that will make the dream come true – we do not know whether the dream will at all come true or has already come true – we are unable to see either.
