זוהר שמות — דף ריא ע”ב

The Garden of Eden below is on earth, but all of this is a supernal secret. The point spoken of has a portion above and a portion below on earth. The lower Garden is the earthly portion of that point. The two Gardens, upper and lower, are the expression of a perfect unity. The secret of the Gardens in the Zohar is that they correspond to the spiritual worlds and reflect the structure of the sefirot.
