Don't say that someone "looks like" someone else.  It's okay to think it, if you're not looking for it.  Here's how it works.. yes, everything is an energy-net.  Yes, there are many so-called variables.  Yes, everyone is unique.  We're each a unique mini-manifestation of the Universe..

Now, face and persona do correspond; however, in between the parametrics of how faces vary and the parametrics of how personae vary is a sort of 'focal point' or hourglass curve.  If you point out how someone looks like someone else, you short-circuit that hourglass, and the more they find out the more they get generified.  It probably has something to do with the vas deferens between the spiritual and the physical, and also that most of the *specifically unique* information in your body is coiled away in your DNA, precise skin tone and texture, smells, etc.

Just don't do it.
