Eden was never a garden, thank Gnon.
Gardens are fake. Eden is not fake.
We never left. Earth always was Eden, and always will be.
If you do not experience it as Eden, you live in a prison of your own making. You were never cast out, you were the one casting. You threw out the holiness of paradise and slammed the door behind it.
And why shouldn't you? Living in a garden is better, right? Your mind is a garden now. You're the gardener. What grows there is nearly under your sole control.
How has living in a garden worked out for you?
All you have to do is put down the flaming sword, and let yourself out.
