Yggdrasil-and all its creatures

I love the story  of  Mimirs Well.  It reminds me of Mary's Waterhole / Miimiga Gaungan,  north of Coffs Harbour.  Sacred birthing place of the original people of this land known now as Australia.

Miimiga Gaungan, located within Sherwood Nature Reserve, is a sacred, spiritually and culturally significant site for Gumbaynggir women. The waterhole is considered to have special healing attributes; preventing miscarriages and ensuring women carried children to their full term safely:  
Sometimes four or more women would perform the ritual in the water and washing themselves as high as the breasts, while asking to Wooroomparahal (God) in the sky to help carry the babies till birth. After white people came to the district, many young Gumbainggeri women began to have miscarriages. They believed that unless they performed this ceremony, they would lose their baby. When they had completed the ceremony, the women were confident their pregnancies would go full term (WetRocks n.d.:1). 

Knowledge of the spiritual healing qualities of Miimiga Gaungan continues to be passed on to Gumbayngirr women needing spiritual and physical healing. Aboriginal women from the local community look after the site and visit periodically to clear leaves and sediment out of the waterhole. Men are forbidden from entering the site (OEH 2013). 4

Mímisbrunnr "Mimir's well" - The second root

This well is known for being the root of all wisdom and knowledge, and its protector is the all knowing Mimir. Mímir, (“The Rememberer”) is an exceptionally wise being and a counselor of the gods. A shadowy being who lived next to the second root at Mimir`s well, and whose knowledge of all things was practically unparalleled among the inhabitants of the cosmos.

Odin achieved this status largely by taking his water from the well, whose waters impart this cosmic knowledge. When Odin arrived, he asked Mimir for a drink from the water. The well’s guardian, knowing the value of such a draught, refused unless the seeker offered an eye in return. Odin 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 Later Mimir was killed and beheaded by the Vanir during the Aesir-Vanir War. Upon seeing the severed head, Odin embalmed it with special herbs and chanted magical songs over it to preserve it. He consults the head in times of need, and it continues to dispense incomparable advice.
