Its said that.

The Eyes are the windows to the soul, WHY?

Because they directly reflect reality.

Only to look someone is to see them and you in there eye,

There reflection of whats going on. Who/ What they are and are thinking of/like.

The iris is the centre of the soul because its black on all people, thats just because black works most like a mirror.

a mirror is just a see through material with the most light absorbant material behing it, <like your iris>

If some one is looking you in the eye there are 3 ways to prove to them you have a soul,deppending If you want them to see you;

A) Reflect what your looking at, be them , be there soul . know the truth . know them absolutly.

b) think in loops and infinity, show them what it is too see infinity (this is good for tricking people)

c) empty your head space Think of true nothingness.

d) all of the above
