Ark of the Covenant, an article, written in 2010, from the Voice of the Cape radio station, covers the history and legends of the Ark quite well.

Here is a video, Nassim Haramein on the Ark of the Covenant in which he speaks about this idea of the Ark as a device, dated 10 Dec 2008.

A moment, if you will, on the “Pillar of fire by night” and “Column of cloud by day” — is there any mention of such an occurrence in any Egyptian history or myth? Or any other record anywhere of such a phenomenon? For, if not, then we must assume that Moses was able to activate it — and activate he did — for forty years! Something, even if it was carefully hidden esoteric knowledge no one had previously achieved — or known to have achieved — even in myth.

Let us speak of the energy of this device.

1. Assume the energy it emitted was constant, whether day or night. It was not triggered by sunlight or the lack thereof.
2. It “inhaled” during the hours of light, and “exhaled” during the hours of dark.
3. Assuming that once it was activated, it just radiated its energy. But what was this energy?
4. What was its actual purpose? Except for a couple of exceptions – like the splitting of the Red Sea and the Jordan, it was used almost exclusively as an instrument of warfare. Of what benefit has it actually been to humanity?
5. It existed before the event at Sinai.
6. Who, or what, was actually creating this pillar of energy that accompanied our people for 40 years?
7. Why (let alone how) did they keep it on for that long a period? Yet, it suddenly stops radiating, as soon as we set foot in the Holy Land, or was it when Moshe Rabeinu died?
8. How many more times was it activated after these 40 years? So far, I know of twice – once to cross the Jordan, and once to bring down Jericho.
9. What was its purpose anyways? What effect did it have upon our people? Why was it necessary to accompany us for 40 years?

It hovered above the Tent of Meeting, which housed the Ark of the Covenant itself.

It is not an instrument. It is an activation mechanism. It uses certain principles, both spiritual and material. Why has no one been able to find it, or to build a replica? Is there a design or method hidden in the writings of the Torah? It seems like it is a multi-layered (or multi-dimensional) template.
