What does the occult symbol on MI5's insignia mean?
As far as I have been studying the missing link is that the eye personifies the sun in the form of the 'lucent light' that of Lucifer sent to earth. Hence the many corporations using the flame, torch, and eye symbols. Lucifer-lucent, the light of the fallen angel ruler of the earth - ties in with devil worship.
Everything but itself
It is rather strange. The only thing I know about the all seeing eye is the old saying. The all seeing eye sees everything but itself.
The Eye of Horus?? Horus was a sun god of Egyptian mythology, usually depicted with a falcon's head [Dictionary definition]
