Ransara,
Yes, in regard of the question, it's possible that one is not aware of certain paths and fruits. As for the Arahat, my person is not sure about it, but one could investigate some situations in the Suttas.
Many do not know their current wealth, but that is mostly good, since it caused suffering thinking "I am this or that", not to speak of questioning "Am I this or that.
So when asking your self or other, simple ask if this or that work has been already done. So if not "the task is done, there is no more further for this world (or a next)" arsises, is know simple: Work, and take on all possible given possibilities for it.
One having done
Not easy to do
Should not be scared
To delight in it
Nor should one
Reject done merits.
For it is hard
To gain such a life
And its even harder
To gain such again:
Meeting either
The good Dhamma
Or upright leading man.
What ever good
Has been done
Achived, sacrified,
Only those delighting,
In deeds hard to do,
Having gratitude,
Form themselves and
In regard of others
Their sacrifies, their deeds,
Are able to carry themseves
Beyound.
Anumodan(e)a!
