I think the story of Adam and Eve refers to the monad's fall through the various levels/dimensions from spirit to matter. I think the different dimensions of existence 'falling' from the Ultimate Source is referred to, without much detail, in Genesis 1, where God creates higher and lower waters, separated by a firmament. Eventually the dry land (the lowest, material level) emerges from the lower waters. It can therefore be considered to have fallen from these higher dimensions.
