The Hanged Man divination

In "Opening the Eye of Vision", The Enchantress with the Eye of Truth stands at the Well at the World's End:

from the Oracle in the liturgy:

A further Initiation leads you at last to reach the Well of Truth, which is both its matrix and its source. Here you meet Me as an ancient woman, hooded in a black cloak. Many dread Me in this form, for I am Death. But as I throw back my hood you see no skull, but rather the Enchantress Who has guided you through many incarnations! You gaze at the still water of the Well and you understand the meaning of all suffering and evil; love and joy. And in this understanding you awaken the Eye of Truth within you. I smile and I embrace you and I hand you my cloak.

The Hanged Man is a card of profound but veiled significance. Its symbolism points to divinity, linking it to the Passion of Christ in Christianity, especially The Crucifixion; to the narratives of Osiris (Egyptian mythology) and Mithras (Roman mythology). In all of these archetypal stories, the destruction of self brings life to humanity; on the card, these are symbolized respectively by the person of the hanged man and the living tree from which he hangs bound. Its relationship to the other cards usually involves the sacrifice that makes sacred; personal loss for a greater good or a greater gain.

Serenely dangling upside-down, the Hanged Man has let go of worldly attachments. He has sacrificed a desire for control over his circumstances in order to gain an understanding of, and communion with, creative energies far greater than his individual self. In letting go, the hero gains a profound perspective accessible only to someone free from everyday conceptual, dualistic reality.

The Hanged Man is often associated with Odin, the primary god of the Norse Pantheon. Odin hung upside down from the world-tree, Yggdrasil, for nine days to attain wisdom and thereby retrieved The Runes from the Well of Wyrd, which the Norse cosmology regarded as the source and end of all Mystery and all knowledge. The moment he glimpsed the runes, he died, but the knowledge of them was so powerful that he immediately returned to life. This interpretation highlights the necessity of undertaking acts of personal sacrifice in order to achieve one's own higher spiritual good.

[Note from Joan: another part of the legend says that Odin gave his physical eye to the Norn Urda so he would be able to see the future.]

Another meaning resides in the journey of life. Certain aspects of life — for example sex — are viewed one way by children and a different way by adults. The Hanged Man is the initiate into mysteries. He understands the Truth because he sees it from a different angle.

The most common interpretation of the card is of an outcast of society that appears to be a fool but is in actuality completely in alignment and integrated. The inversion of The Hanged Man furnishes an advantage opaque and impenetrable to others

Runes

The eddic poem explains that their originator was the god Odin, and Stanzas 138, 139 describe how Odin received the rune through his self-sacrifice. The text (in Old Norse and in English translation) is as follows:

Veit ec at ec hecc vindga meiði anetr allar nío,geiri vndaþr oc gefinn Oðni,sialfr sialfom mer,a þeim meiþi, er mangi veit, hvers hann af rótom renn.
Við hleifi mic seldo ne viþ hornigi,nysta ec niþr,nam ec vp rvnar,opandi nam,fell ec aptr þaðan.

I know that I hung on a windy tree nights all nine,wounded with a spear and given to Odin,myself to myself,on that tree of which no man knows from where its roots run
No bread did they give me nor a drink from a horn,downwards I peered,I took up the runes,screaming I took them,then I fell back from there
