The extraordinary acoustic properties of the tomb deserves some further explanation.
First of all, the tomb itself presents solid evidence that ancient peoples knew a great deal more about architecture and acoustic property than anyone gives them credit for today. The article reveals that the structure was built with a great deal of attention to detail in order to produce certain rates of vibration; and we can be certain that this temple is not a one-off, that is, it did not spring whole from the earth without predecessors. The people who built this temple came from a long-standing tradition of peoples who investigated the acoustics of space, and had a very sophisticated understanding of them — so sophisticated that we are only just now beginning to grasp them ourselves. This means that the culture that built this temple (and, as we shall see, it is not just a tomb, but a temple, both of which purposes were intentional from the outset) was already an ancient one when the temple was built; their architectural sciences were mature and elaborate.
Secondly, these ancient peoples knew a great deal about the principles of vibration, the purpose it serves, and how to implement its use in sacred ritual.
As I have explained on numerous occasions, the position la or seven on Gurdjieff's enneagram represents purification, and falls in the position of the throat chakra in the yoga system. (This is explained in considerable detail in my book The Universal Enneagram.) As I indicated in posts in late June, (See the dominant force: meditations on death) purification is the most essential step for the development of Being as it completes its cycle around the perimeter of the enneagram; and death permeates the entire left side of the diagram.
It was no accident that ancients associated vibration with purification. This is why purification rituals are always marked by prayer and hymnal; it is one of the most ancient traditions in the world to associate musical action and speech with purification ritual. This is because purification always results in the refinement of vibrations to more harmonious, compatible relationships out of the primary chaos that vibration exists in in every being. Indeed, all of the material arises from the reorganization of the primal chaotic quantum vibration of reality into organized form; so even the arising of the material represents the first step in purification, the alignment of vibration to serve a higher order.
Ancient peoples understood this; and by the time the Hypogeum was built, the sciences surrounding this were mature, so mature that we marvel at them today. They make an indelible impression on the soul, simply because the people who designed these spaces understood how that worked. And that impression on the soul was an important one; because as well as serving as a "primitive" bonding ritual (which is about as far as our modern day archaeologists and anthropologists can take us) its most essential character was expressed in the physical or organic experience of our own mortality, as it relates to the alignment with a higher or sacred vibration.
Gurdjieff maintained that human cultures were unimaginably more ancient than we can know; and buildings like this, which represent what was the tail end of much more harmonically attuned cultures which died out with the advent of "civilization," are the evidence that as of 5000 years ago, men still understood and preserved ancient sciences that probably date all the way back to the temples found at Göbekli Tepe; and, of course, even earlier, because the temple at Göbekli Tepe did not spring hole from the earth. At about 11,000 years old, it already represents a mature and sophisticated architecture and symbolic language which must have developed over several thousand years at a minimum.
Most of the ancient cultures that produced these extraordinary temples inhabited areas near rivers and the seaside which were flooded by the melting of the great glaciers after the last Ice Age. Because our underwater archaeology is primitive, little or no attention has been paid to the exploration of sites that would reveal the much more ancient roots of human culture; when they are discovered, we will see that man had sophisticated architectural, cultural, and spiritual understandings long before we assign them to the cultures we excavate today. Gurdjieff argued that these ancient cultures had, in many cases, understanding superior to our own; and the Hypogeum at Malta represents an echo of that.
More on the subject tomorrow.
