A huge, brain-shaped, pallid, underground tuber mirrors the green brain tree above. Based on the idea that a real tree occupies as much space underground as it does above ground. A surreal, New Age graphic with roots in magic and the occult (think of the mandrake pulled, and "as above, so below"). This design illustrates the split between the earthly and divine, or the hard problem of consciousness (qualia from mud). Earth to earth... The gut-brain axis. Cerebral vs visceral. Origins of thought.
