Your taking as close a glimpse into eternity as one can. You are looking at you looking at you looking at you. Perpetual you.
This is, of course, assuming that you are perpetual. I cannot say I have ever felt that sense of myself when looking in a mirror.
Which any person will do if they permit the self-examination that tends from the act
You find self-reflection while gazing at yourself in a mirror?
We spend a lot of our time escaping ourselves and to look into ones own eyes allows no escape from yourself.
Well I have found no answer for the tendency to escape from life by looking in a mirror since, to me, this is simply another escape of sorts. Deep introspection, for myself, is not found by simply examining oneself, however deeply, but by observing oneself through interaction with others.
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
This is only a problem if you have a mindset that forces you to view the world as such. For myself, there is no such supernatural fear driving my reflection of myself. Sin is a connotation that extends beyond the actual wrong that is descibed by the sin. Not all sins are black and white and many are of far greeater complexity than simply being a violation of some ancient injunction against such behaviour.
It is not spooky in the least unless you assign a belief to frame it so in your mind. I find it sad that such is your lot in life and I cannot personally share your fear of the world.
Dear Mrs Chown, Ignore your son's attempts to teach you physics. Physics isn't the most important thing. Love is.
