The 3rd Eye, Shiva and the Eye of Wadjet

I want to explain the objectively non-spiritual, but enlightening background of the 3rd Eye, the Pineal Gland which can be associated with the 3rd Eye, and you can choose to then realize how the Spirit World overlaps this one or not:

There are parts of your Brain that can be removed and you will still function. They used to Labotamize people by sticking a rod in their nose and pushing it back and forth through the person's brain, and people have had been axed in the head and face in bed, and woken up to walk around and do their morning routine before dying, or not dying.

Lizards actually have lenses on their Pineal gland, and in some it protrudes from the forehead.

At some point, before Dinosaurs, when the first Multicelled Organisms were starting to developed brains, there was likely an organism that had a Sensor Directly from the Brain to the outside world, that then developed into Sight, Hearing, Touch, Taste, etc. We are far off from understanding the Human Brain, and this could even be left over from the Original Multicelled Organisms.

So when Shiva, the God with the 3rd Eye, is said to have invented Meditation, he invented a way to reach back into the part of our Brain that seems to have been there before we could See or Hear. Before anything could See or Hear.

In Ancient Egypt the 6th sense was Thought, related to Thoth, which the Ptolemics interpreted as Hermes. This Symbol was created by the Ancient Egyptians in order to allow the Dead to See.
