Why do the Occult injure one eye?
Why Odin is One-Eyed??
https://norse-mythology.org/tales/why-odin-is-one-eyed/
Odin’s quest for wisdom is never-ending, and he is willing to pay any price, it seems, for the understanding of life’s mysteries that he craves more than anything else. On one occasion, he hanged himself, wounded himself with his spear, and fasted from food and drink for nine days and nights in order to discover the runes.
On another occasion, he ventured to Mimir’s Well where there dwelt Mimir, a shadowy being whose knowledge of all things was practically unparalleled among the inhabitants of the cosmos. He achieved this status largely by taking his water from the well, whose waters impart this cosmic knowledge.
The well’s guardian, knowing the value of such a draught, refused Odin a drink from the well unless the seeker offered an eye in return. Odin – whether straightaway or after anguished deliberation, we can only wonder – gouged out one of his eyes and dropped it into the well. Having made the necessary sacrifice, Mimir dipped his horn into the well and offered the now-one-eyed god a drink.[2][3]
The most general and obvious message of this tale is that, for those who share Odin’s values, no sacrifice is too great for wisdom
The fact that Odin specifically sacrificed an eye is surely significant. In all ages, the eye has been “seen” as a poetic symbol for perception in general – consider the astonishing number of expressions, both in everyday usage and in the works of the great canonical poets, that use vision as a metaphor for perceiving and understanding something. Given that Odin’s eye was sacrificed in order to obtain an enhanced perception, it seems highly likely that his pledge of an eye symbolizes trading one mode of perception for another.
