You've brought up an excellent point Ginnyrose.
It has nothing to do with "pretty eyes" as the world thinks it and I know that is exactly what you are meaning by your question - Amen!
I for one feel at a horrible disadvantage talking with people who I haven't spoken with 'face to face' because there is so much in the eyes of us all. I've met people who were always happy, but when I looked into their eyes I saw a "hurt" in there and they were really hurting inside.
What I notice most is with those with no guile - their eyes are like pools that you can go right into but if there is any fascade or non-genuiness, their eyes are like brick walls saying "don't enter." You can see hatred in eyes, even if the rest of the face is smiling. It's not an "art" like FBI work nor like some New Age practice, but when you're talking with folks, many times you can catch where they are hurting by their eyes and other traits & feelings. Can they even make long term eye contact and if not why? The Holy Spirit is the only one that knows. Sometimes they're just feeling false-guilt or feeling inadequate or really do have a problem. I really love eye contact with anyone I'm talking with. It's actually quite precious - but yes, sometimes it can reveal some very scarey things.
I was on a forum where they posted their pictures by their names and one woman always posted very meekly and kind but every now and then, I'd be caught by her eyes in the picture where she had a half of a smile and saw 'hatred' in those eyes and later found out that was very much the case.
As you know, eyes can be beautiful to the world, but what you see 'in' them may not be beautiful at all - especially if what you're seeing in them is pain, hurt, sadness, etc..
Now these eyes are some of my favorite. I can sink into these like a healing pool - even though the world would see nothing "beautiful" in them - [url=https://www.sermonindex.net/modules/myalbum/photo.php?lid=198]Photo[/url] :-D .
