"Eden"…

is the Insular Cortex, aka the Island.

'Eden' within. First part of the physical 'brain' to form, from which Gen 2:10 occurs/describes:

"And a river went out of Eden to water the garden; and from thence it was parted (Lateral Sulcus), and became into four heads." (Four lobes of the brain parietal, occipital, frontal, and temporal aka Pison, Gihon, Hiddekel, and Euphrates)

Eden, the word, comes from Norse Idun, the goddess of spring or rejuvenation, the keeper of the magic apples of immortality.

Every physical place has a 'God' or energy over it. Eden and Idun are one in the same.
