There are perspectives of "Seeing and Hearing" , all of which perceives information.

Now , with my physical eyes I can perceive (sight);
With my skin, I can perceive " feeling"
With my nose , I can perceive Odour or Scent.

So, with the right Spiritual Connectivity, MEN can be connected to God , which could mean SEEING GOD.
What matters is PERCEIVING GOD, not necessarily by Sight.

Infact sight perception is not necessary because GOD is a SPIRITUAL Powerforce; not a Physical, Observable Substance which can be perceived by our Physical RETINA.

Yes! I have "Seen" God and I am not a Lunatic!!
