Helm of Awe

Helm of Awe norse symbol, viking spiritual symbol
The Helm of Awe is often confused with the Vegvisir because of their visual similarities. However they are quite different
The Helm of Awe, often called "Algiz" or the "Helm of Terror", was worn in battle as a sign of strength and a form of protection. 
The symbol was usually worn by warriors in the middle of their brow, believing it would grant them victory in battle, like it did for the Dragon Fafnir. The Dragon Fafnir, in the Poetic Edda, claims he was invincible by bearing the Helm of Awe:

The Helm of Awe
I wore before the sons of men
In defense of my treasure;
Amongst all, I alone was strong,
I thought to myself,
For I found no power a match for my own.
"Though maybe a coincidence, there are a couple other ancient symbols that bare some resemblance. In Buddhism, the dharma wheel, which protects the hearth and is said to be the pathway to enlightenment also has 8 spokes in a circular shape. There is evidence of the Norse people migrating out of the Indian subcontinent, so the similarity is intriguing. Especially so when you consider that Norse warriors would usually place the Aegishjalmr between their eyes. The location of the third eye according to Indic beliefs. The third eye is said to see past the material world and into the spiritual world, and the Aegishjalmr is said to strike fear or awe in the hearts of enemies. Perhaps it is coincidence but the connection between these two peoples makes me question if there is validity to this claim."
