One of the questions / answers recently posted here was about "storing" mental states for later.
Of course this isn't Buddhist, in the sense that it does not literally describe a selfless person.
But it could be metaphorical, couldn't it? The idea that the mind is like a computer, even though there are dis-analogous elements to that term, there are overlaps - like the way that persons have access to the past in memory, as if they were "stored".
So my question is: are any of the Buddhas actual teachings only metaphorical?
