Your taking as close a glimpse into eternity as one can. You are looking at you looking at you looking at you. Perpetual you.
We spend a lot of our time escaping ourselves and to look into ones own eyes allows no escape from yourself. You are locked into looking at yourself for once - with the only form of escape being to look away again
Which any person will do if they permit the self-examination that tends from the act. There is even more reason to look away from ones own eyes as there is those troubled eyes you catch on the street from time to time - and look away from. You can see the trouble in your own even better
No place to run or hide. One must look away. Looking at a dead spirit is looking at death. It is spooky. Or looking at an alive spirit which is still a sinner. For sin is ugly
One of the benefits of heaven - you can finally look into your own eyes. What pretty eyes they must be
This thing I'm looking at in the mirror is not dead. It's just not me.
OK, now I get it. Sort of. In my case it's probably just the melancholy fact of aging, though you may mean something more existential about it. Yes, that's definitely not me in the mirror NOW. I was willing to own her up to, oh, maybe twenty years ago.
