Ancient Egypt, like that of the Olmecs (Bolivia), emerged all at once and fully formed. Indeed, the period of transition from primitive to advanced s… - Graham Hancock

Another scene from universal myth unfolds — here powerfully reminiscent of the Underworld quests of Orpheus for Eurydice and of Demeter for Persephone. The ancient Japanese recension of this mysteriously global story is given in the Kojiki and the Nihongi, where we read that Izanagi, mourning for his dead wife, followed after her to the Land of Yomi in an attempt to bring her back to the world of the living:
'Izanagi-no-Mikoto went after Izanami-no-Mikoto and entered the Land of Yomi ... So when from the palace she raised the door and came out to meet him, Izanagi spoke saying; 'My lovely younger sister! The lands that I and thou made are not yet finished making; so come back!'
Izanami is honoured by Izanagi's attention and minded to return. But there is one problem. She has already eaten food prepared in the Land of Yomi and this binds her to the place, just as the consumption of a single pomegranate seed binds Persephone to hell in the Greek myth.
Is it an accident that ancient Indian myth also contains the same idea? In the Katha Upanishad a human, Nachiketas, succeeds in visiting the underworld realm of Yama, the Hindu god of Death (and, yes, scholars have noted and commented upon the weird resonance between the names and functions of Yama and Yomi). It is precisely to avoid detention in the realm of Yama that Nachiketas is warned:
'Three nights within Yama's mansion stay / But taste not, though a guest, his food.'
So there's a common idea here — in Japan, in Greece, in India — about not eating food in the Underworld if you want to leave. Such similarities can result from common invention of the same motif — in other words, coincidence. They can result from the influence of one of the ancient cultures upon the other two, i.e. cultural diffusion. Or they can result from an influence that has somehow percolated down to all three, and perhaps to other cultures, stemming from an as yet unidentified common source.

Since my first research visit to Malta in November 1999 I've learned that objects — and even places — of archaeological importance can and do disappear here in mysterious ways. For example, ancient remains of an estimated 7000 people were found in the Hypogeum of Hal Saflieni, buried in a matrix of red earth, when it was excavated by Sir Themistocles Zammit at the beginning of the twentieth century. Today only six skulls are left, stashed out of public view in two plastic crates in the cavernous vaults of Malta's National Museum of Archaeology. Nobody has the faintest idea what has happened to all the rest of the bones. They've just 'vanished', according to officials at the Museum.
And the six skulls? After much pressure and protest I have been allowed to see them only this morning and they are — I must confess — extremely and unsettlingly odd. They are weirdly elongated — dolichocephalic is the technical term but this is dolichocephalism of the most extreme form. And one of the skulls, though that of an adult, is entirely lacking in the fossa median — the clearly-visible 'join' that runs along the top of the head where two plates of bone are separated in infancy (thus facilitating the process of birth) but later join together in adulthood. I should be paying attention to the fantastic views and seascapes unfolding beneath the helicopter but I keep on wondering: what would people with skulls like that have looked like during life? How could they have survived birth and grown to adulthood? And did the other skulls from the Hypogeum — the lost skulls, the lost bones — also show the same distinctive peculiarity?

We have severed our connection to spirit. That's what our society has done. It has sought to persuade us that the material realm is the only realm. And the only way we're going to recover is to reconnect with spirit. And I truly believe we need the help of the plants in order to do that.
